Introduction to JavaScript: Basics |
https://dev.to/nehasoni__/introduction-to-javascript-basics-g6n
|
Introduction to JavaScript BasicsHello amazing people In this blog article I am going to explain the basics of javascript Let s get started This Blog post will cover What is JavaScript How JavaScript is different from other programming languages like Java or C How to include JavaScript in your HTML page How to Write Comments in JavaScript Variables in JavaScript Data types in JavaScript Operators in JavaScript Conditional Statements in JS Loops in JavaScript Functions in JavaScript PrerequisitesBefore starting this article you don t need any previous JavaScript knowledge but you should have some familiarity with HTML and CSS Introduction to HTML Introduction to CSS What is JavaScript JavaScript is a scripting language used to create and control dynamic web content It is an interpreted lightweight object oriented programming language that enables dynamic interactivity on websites It can be anything from animated graphics to an automatically generated Facebook timeline Once you have created your basic structure HTML and elegant vibe CSS JavaScript makes your website dynamic automatically updateable If you are a software developer gravitated towards web development then you must learn javascript and once you have learned JavaScript there are many frameworks available which you can use to create multiple web applications Nowadays javascript is also used in mobile app development desktop app development and game development This opens many possibilities for you as a JavaScript developer How JavaScript is different from other programming languages like Java or C The major difference is that JavaScript is a scripting language i e it is not compiled and executed like C and java It is dynamically typed whereas Java or C is statically typed JavaScript is traditionally used to write scripts for web applications The client receives the whole source of the script and the browser executes it the browser has a JavaScript interpreter while the browser couldn t execute Java or C programs Javascript does not support multithreading while java or C is a multi threaded language Now javascript can run on the server via Node js How to include JavaScript in your HTML page JavaScript can either be embedded directly inside the HTML page or placed in an external script file and referenced inside the HTML page There are three places to put javascript code between head tag of HTML pageExample lt DOCTYPE html gt lt html gt lt head gt lt meta charset utf gt lt title gt Embedding JavaScript lt title gt lt script gt document getElementById greet innerHTML Hello World lt script gt lt head gt lt body gt lt div id greet gt lt div gt lt body gt lt html gt between body tag of HTML pageExample lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset utf gt lt title gt Embedding JavaScript lt title gt lt head gt lt body gt lt div id greet gt lt div gt lt script gt document getElementById greet innerHTML Hello World lt script gt lt body gt lt html gt In js file external javascript file Example index html lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset utf gt lt title gt Linking External JavaScript lt title gt lt head gt lt body gt lt div id greet gt lt div gt lt button onclick greet gt Show message lt button gt lt script src script js gt lt script gt lt body gt lt html gt script jsfunction greet document getElementById greet innerHTML Hello World How to Write Comments in JavaScript Comments are a meaningful way to deliver messages It is not necessary but recommended to use comments to add information about the code warnings or suggestions so that others can easily understand and interpret your code Types of comments in javascriptSingle line comment gt Single line comments are represented by double forward slashes Example lt script gt var x var y var z x y It adds values of x and y variable document write z prints sum of x and y lt script gt Multi line comment gt It is represented by forward slash with an asterisk then asterisk with forward slash Example lt script gt The code below will change the heading with id myP and the paragraph with id myP in my web page document getElementById myH innerHTML My First Page document getElementById myP innerHTML My first paragraph lt script gt Variables in JavaScriptVariable means anything that can vary These are the containers for storing data values Also JavaScript variables are loosely typed which means it does not require a data type to be declared There are some rules while declaring a variable in js variable name must starts letter a to z or A to Z underscore or dollar sign after the first letter we can use digits to for example abc javascript variables are case sensitive x and X are different variables Example of JavaScript variablesCorrect JavaScript variables gt lt script gt var x var value var flag true var Name declaration of variableName neha initialization of variable lt script gt Incorrect JavaScript variables gt lt script gt var var aa lt script gt There are two types of variables in javascript Local variables Global Variables JavaScript local variable gt Local variables are the variables that are defined inside block or function They have a local scope which means that they are accessible within the function or block Example lt script gt function fun var x local variableconsole log x lt script gt JavaScript global variable gt Global variables are the variables that are defined outside the functions or declared with a window object They can be accessed from any function Example lt script gt var data global variable function a console log data function b console log data a calling JavaScript function b lt script gt Data types in JavaScriptData types basically specify what kind of data can be stored and manipulated within a program JavaScript provides different data types to hold different types of values In JS we don t need to specify the type of the variable because it is dynamically used by the JavaScript engine Mainly there are two types of data types in javascript Primitive data types Non Primitive data types Primitive data types Primitive data types can hold only one value at a time There are five types of primitive data types in JS Non primitive data types Non primitive data types can hold collections of values and more complex entities There are mainly three types of non primitive data types Operators in JavaScriptOperators are special symbols used to perform operations on operands For example var a b var sum a b Here the operator that performs addition and a and b are operands JavaScript Arithmetic OperatorsArithmetic operators are used to perform arithmetic calculations The arithmetic operators are as follows JavaScript Assignment OperatorsAssignment operators are used to assign values to variables The following are assignment operators in js JavaScript Comparison OperatorsComparison operators compare two values and return a boolean value either true or false The following are Comparison operators in js JavaScript Bitwise OperatorsBitwise operators perform operations on binary representations of numbers The bitwise operators are as follows JavaScript Logical OperatorsLogical operators perform logical operations and return a boolean value either true or false The following are logical operators in js Conditional Statements in JSConditional statements control behavior in JavaScript and determine whether or not pieces of code can run JS if StatementThe most common type of conditional statement is the if else statement This statement only runs if the condition enclosed in parentheses is true There are three forms of if statement in JavaScript If StatementIf else statementif else if statementIf statement example lt script gt var a if a gt alert value of a is greater and equal to lt script gt if else statement example lt script gt var a if a gt alert value of a is greater and equal to else alert value of a is less than lt script gt if else if statement example lt script gt var a if a gt alert value of a is greater than else if a alert value of a is equal to else alert value of a is less than lt script gt JS switch StatementSwitch statement is used to execute one code from multiple expressions If there is a match the associated block of code is executed and if there is no match the default code block is executed Example lt script gt var grade C var result switch grade case A result A Grade break case B result B Grade break case C result C Grade break default result No Grade alert result lt script gt Loops in JavaScriptLoops are used for executing a block of statements repeatedly until a particular condition is satisfied It makes the code compact JavaScript supports different kinds of loops for loop for in loop while loop do while loop JS For loopThe for loop iterates the elements for the fixed number of times Syntax of for loop is as follows for initialization condition increment code block to be executed Example lt script gt for i I lt i document write i lt script gt Output JS For in loopThe for in loop iterates through the properties of an Object Syntax of for loop is as follows for key in object code block to be executed Example lt script gt var user var person fname Neha lname Soni age var x for x in person user person x document write user lt script gt Output Neha Soni JS while loopThe while loop iterates through a block of code as long as a specified condition is true Syntax of while loop is as follows while condition code to be executed Example lt script gt var count while count lt document write count count lt script gt Output JS do while loopA do while loop is similar to a while loop with one exception that the code is executed at least once whether condition is true or false Syntax of do while loop is as follows do code to be executed while condition Example lt script gt var i do document write i lt br gt i while i lt lt script gt Output If you want to learn more about loops Click here Functions in JavaScriptFunctions are one of the major pillars of JavaScript It is a set of statements that performs some tasks or does some computation and then returns the result to the user It helps you to divide a large program into small and makes a program a lot more efficient The syntax of declaring a function is given below function functionName arg arg argN code to be executed Let s first see the simple example of a function in JS that doesn t have any arguments lt html gt lt body gt lt input type button onclick msg value call function gt lt script gt function msg function definition alert Hello amazing people create an alert in browser lt script gt lt body gt lt html gt Function Parameters and Arguments gt When you begin programming you may get confused between these two terms but it is crucial to understand what they are and how are they different from each other So Let s understand the difference between these two To learn more about parameters and arguments Click here Function with Return Value gt This is an optional JavaScript statement that returns a value from the function We use the keyword return followed by the statement or expression we want to return Example lt html gt lt body gt lt p gt What is the value of PI lt p gt Ans lt span id demo gt lt span gt lt script gt document getElementById demo innerHTML getPI function getPI return Math PI lt script gt lt body gt lt html gt Note Return statement should be written in the last because it skips all code in the block written after that Function Scope gt As we know there are two types of variables in JS local variables and global variables Local variables are defined inside a function and cannot be accessed outside it But a function can access any variable defined as a global variable Let s understand exactly what I mean with the help of following code lt html gt lt body gt lt h gt Function Scope lt h gt lt script gt var num global variable document write Value of number is num lt br gt global scope function parentFunction var num local variable num document write Number is num lt br gt inside parent func document write Number is num lt br gt local scope childFunction child function called function childFunction nested function var num document write Number is num lt br gt inside child func document write Number is num lt br gt local scope parentFunction parent function called lt script gt lt body gt lt html gt Output Conclusion HTML is the language of web content but JavaScript is the language of web functionality It is one of the fastest evolving languages in terms of practices tooling and ecosystem It s an incredibly exciting language to be using right now In this blog we have just scratched the surface of JavaScript If you enjoyed learning and find it useful please do like and share so that it reaches others as well Thanks for reading I would to connect with you at Twitter LinkedIn GitHubLet me know in the comment section if you have any doubt or feedback

Why you should definitely use NgRx Store |
https://dev.to/this-is-angular/why-you-should-definitely-use-ngrx-2pf2
|
Why you should definitely use NgRx StoreWhen I was a guest on Tech Talks with Santosh agreat talk show hosted by Santosh Yadav I expressed a verycontroversial opinion If your application is big enough to use Angular it is big enough to use NgRxOf course this is my opinion and in general this is an opinionated article but I will try my best to provide arguments why I think it is right for every Angular application to use NgRx The reward is much larger than the riskOf course if you have a team of people that have never worked with NgRx starting a new project using another technology and a new way of thinking can seem like a big challenge and surely some aspects of reactive programming and Flux design pattern and the need to use RxJS extensively can be somewhat confusing but my experience with NgRx made me think that with some dedication it is possible to switch from an imperative mindset to functional programming It is truly possible to come to a decent level of understanding of Flux and NgRx within several days because Concepts are not as complex as they sound at first Actions Reducers and Effects are scary words it seems but in reality an action is a unique object representing an event in state a reducer is a pure function that changes the state according to an action pure functions are especially easy to understand and so on In essence learning NgRx is not very easy but it is not as challenging as learning an entire new framework like Angular itself and definitely worth the time invested in it Once one of the concepts is mastered the next is much easier to understand When you learn about actions and then see them dispatched it becomes easy to understand what a reducer is then what a selector is and after we have learned all of those concepts it will be easy to understand Effects and then suddenly we know NgRx and use on a daily basis Note I would suggest not using NgRx only when there is a lack ofbasic knowledge of RxJS but if you know basic operators map filter startWith and Observable combination combineLatest mergeMap you are good to go to start learning NgRxSo basically NgRx is not as hard to learn as one might imagine and learning it will yield immense benefits So if your or your teams policy on NgRx is it is too much overhead to learn and switch to it then it is time to rethink that policy The reward is not only larger than the risk but it is also hugeNgRx allows us to have three important things in our applications A single source of truth for all our data This means we can easily understand where and when the data changed and how it affected our UI Because of its centralized structure problems are easy to detect if the state changes in an unexpected way then the problem is in the reducer function if the state is transformed in a wrong way then the problem is in the selector and so on It provides a clear almost mechanical pathway of solving frontend related challenges making applications extremely scalable In other words NgRx provides a simple yet very strict structure for how our frontend application should function even on the folder structure level It also makes of tasks and UI pieces very straightforward Because of its awesome devtools it is very easy to debug follow and understand when and where something went wrong Essentially these three points help us have an application that is as maintainable and scalable as possible And this is not something theoretical you will become convinced of this as soon as you get your first feature requirement change after a certain feature is already built Imagine scenario we have an app where once a user selects a value from a dropdown in one component an HTTP request is performed and if it is successful another HTTP request should be performed and update a piece of UI in another component Now imagine changing the codebase according to this requirement in an application that does not use NgRx First we would need a transport mechanism to notify the other component of the dropdown value change a service with a subject or something like that then we would need to subscribe to that notification in the other component and don t forget to takeUntil to unsubscribe then inject a new data service into that component perform the HTTP call get the data store in the local state update UI Lots of steps is it not Now imagine the same in NgRx if the state is already selected in the second component we would just need to dispatch another action in the corresponding Effects class probably lines of code if not then add a select method call most probably just line of code and it is all done Understandable clean easy to reason about almost bug free In reality Angular apps with NgRx are more understandableSometimes developers may think that introducing a new framework of thinking will just increase complexity and make applications harder to navigate and perceive But the NgRx experience proves yet again that it is better to have more lines of code that are explicit and strict rather than a short but disorganized one Without NgRx the application s overall situation is not readily understandable It is not clear on what data the components depend also it is hard to tell only from code how components affect each other But with NgRx the connections are very clear data flows only from one place through one place and is immutable All of this makes our applications very easy to get into if you want to know how the state can change take a look at action names if you want to know exactly how read the reducer function which is usually very obvious as most pure functions are if you want to know which data is loaded from external sources read an Effect In conclusionNgRx is not just a library or a tool it is a way of thinking and before you start doing it there is a learning curve to ascend and concepts to accept but in the end when the learning process is done you will find out how much it benefits your development process In several months it will be harder to do Angular without NgRx |
