海外TECH	DEV Community	Why you should learn JavaScript and Python in 2022	https://dev.to/andrewbaisden/why-you-should-learn-javascript-and-python-in-2022-3719	Why you should learn JavaScript and Python in A new year brings new opportunities for aspiring developers and people who are trying to leave their non tech role so that they can get hired as a developer One of the most common dilemmas that these people face is figuring out what technical stack to learn and in what direction they should be going when it comes to learning a new programming language from scratch There are endless options and many different paths that someone could choose to go down Arguably two of the most popular and talked about programming languages in the world are JavaScript and Python If you search for JavaScript and Python job roles on any job board you are highly likely to see hundreds if not thousands of results The market is and always will be hot for these two highly sought after languages and that is not going to change anytime soon Both languages share quite a few similarities as well They are both C based languages which essentially means that they are general purpose procedural and have lexical scopes among other things Dynamic vs StaticOne of the biggest standout points is the fact that JavaScript and Python are dynamically typed languages In a manner of sense a dynamically typed programming language does not require variables to be explicitly declared prior to their usage And in the reverse a statically typed programming language prevents variables from getting reassigned to a different type All of this will become more clear in the examples below Java ExampleString myName Variable with a type of stringmyName Tony Stark The string is called Tony StarkmyName Reassigning the string into a numberIf you were to run this Java code you would get either a compile error or runtime error It is not possible to reassign static types to a different type You can only use another string like Steve Rogers JavaScript Examplelet myName Variable that has no typemyName Tony Stark The variable has a type of stringmyName The variable has changed its type dynamically to a number Now if you were to run this JavaScript code you would get no errors as it is perfectly valid The variable name is now the number Python Examplemy name Tony Stark The variable has a type of stringmy name The variable has changed its type dynamically to an int Similarly if you were to run this Python code you would also get no errors as it is perfectly valid The variable name is now the Int Data TypesData types are essentially ways to store data inside of an application The type of data type specifies what can be stored and how it can be managed Below you will find a list of some of the data types that each language has JavaScript Data TypesText Type stringNumeric Type numberBoolean Type booleanMapping Type objectSequence Type array Python Data TypesText Type stringNumeric Type int float complexBoolean Type booleanMapping Type dictSequence Type list tuple range Comparing the syntaxNext we will compare the syntax for both programming languages so you can see how easy it is to transition between the two of them First let me run through a few differences between the languages JavaScriptUses semicolonsUses curly braces for code blocksUses the CamelCase naming convention for variables for example firstNameUses console log for outputting messages to the consoleFunctions use this syntax function myFunc console log Hello World const myFunc gt console log Hello World myFunc myFunc PythonDoes not use semicolonsDoes not use curly bracesUses the Snake Case naming convention for variables for example first nameUses indentation for code blocksUses print for outputting messages to the consoleFunctions use this syntax def my func print Hello World my func TextBoth languages output a string type variable JavaScript Syntaxlet myName Tony Stark console log typeof myName string Python Syntaxmy name Tony Stark print type my name str NumericIn this example both variables output a number in JavaScript JavaScript Syntaxlet num let num console log typeof num Numberconsole log typeof num Number Python SyntaxIn this example Python is able to see the difference between a number and a float because they are built in data typesnum num print type num Intprint type num Float BooleanThe output is almost exactly the same the only difference is that JavaScript uses a lowercase t for true whereas Python uses an uppercase T JavaScript Syntaxlet wizard true console log wizard boolean Python SyntaxIn this example Python is able to see the difference between a number and a float because they are built in data typeswizard Trueprint wizard bool MappingJavaScript uses the object data structure whereas Python uses the dictionary data structure From looking at the examples you can see that they are very alike The difference is that JavaScript does not require quotes for the keys whereas Python requires them for the keys in the key value pair The keys are on the left for example name and the values are on the right for example Tony Stark JavaScript Syntaxconst myprofile name Tony Stark age superhero Iron Man console log myprofile Python Syntaxmy profile name Tony Stark age superhero Iron Man print my profile SequenceJavaScript uses an Array which is a type of object data structure whereas Python uses the list data structure As you can see they have many similarities in terms of the syntax you write JavaScript Syntaxconst myArr console log typeof myArr object Python SyntaxmyArr print type myArr list Where to go from hereThere are many platforms you can go to if you want to learn JavaScript and Python Personally I think that freeCodeCamp and Udemy have great courses for both of them These are the ones that I recommend Learn JavaScript Learn Python	2022-01-04 10:25:38

海外TECH	DEV Community	How Does JavaScript Even Work? Things Which 90% of JavaScript Developers Don't Know! (Part 1)	https://dev.to/saiteja13427/how-does-javascript-even-work-things-which-90-of-javascript-developers-dont-know-part-1-145b	How Does JavaScript Even Work Things Which of JavaScript Developers Don x t Know Part JavaScript was initially developed as a frontend scripting language to fulfil the lacking dynamic behaviour of the web by Brendan Eich of Netscape for their Netscape Navigator browser From there Javascript has today grown into such a huge ecosystem that you can develop applications on the web mobile and desktop with just javascript which is impossible with any other language Now if you have ever worked with JavaScript you would have heard that Javascript is single threaded non blocking and it is asynchronous as well Isn t that counter intuitive How can something be single threaded and asynchronous as well Well there are a lot of such things in JS and to understand it all you need a deep dive into JS and its working So let us try and understand the working on javascript which of JS developers don t know Firstly let us see what is ECMA and what do these specifications tell us about JavaScript ECMA ScriptECMA basically stands for European Computer Manufacturer s Association and it defines a trademark standard for scripting languages like JavaScript and the JScript Developed by Microsoft You would have heard ES ES while working with JS the ES here stands for ECMAScript ECMA puts a lot of specifications in place related to notations operations syntax functions classes etc You can refer to all these specifications here ECMAScript But ECMA doesn t have any documentation on the event loop non blocking asynchronous JS Hmm so where do we go now We go to the JS engines Note If you want to read more about the advent of JS and its whole history here is a fantastic blog Why are we creating a JavaScript only World Wide Web JavaScript EnginesA JavaScript engine is basically a software that executes JavaScript code There are various Javascript engines available The most famous engines among the modern Just in Time Compilation engines are V Developed by Google Used in chrome Node js runtime Deno runtime Spider Monkey Developed by Mozilla Used in Firefox WebKit Developed by Apple Used in Safari Chakra Developed by Microsoft Used in Internet Explorer Check out the list of all JS engines here List of ECMAScript engines Wikipedia Now as V is the most used javascript engine from now whatever we discuss will be its implementation Though the other mentioned engines are also similar with a few differences So the V engine is what makes Javascript single threaded as it comes with a single call stack also called as the execution stack or single thread The V engine comes with two main components which are Call stack This is where all the execution happens Heap This is where the memory allocation happens But even standalone V doesn t make JS asynchronous So how does it become asynchronous Keep Reading So let us try to understand the single threaded nature of JS first and what does it mean Then we will see how does it become asynchronous and what problem does it solve Javascript and the Single ThreadLet us get this single thread concept right Javascript being single threaded means that there is only one call stack provided by the engine All the execution happens one block after another in a sequential way That means that all the upcoming code should wait until the current block of code is being executed One Thread One Call Stack One Thing at a TimeThis is called the synchronous execution of code Note Let me tell you that Javascript can be multithreaded as well for example we can use multiple threads in Node js using a module called worker threads So why do people call JavaScript a single threaded language It is because of the implementation of JS engines like V in the browsers which makes JS single threaded because these engines have got only one call stack as already mentioned Now as you understood this let us try a few programs with the main thread to understand the call stack and the problem with it Continue Reading the Blog Here	2022-01-04 10:20:29
