海外TECH	DEV Community	How to build a Flash Title Notification with JavaScript	https://dev.to/unclebigbay/how-to-build-a-flash-title-notification-with-javascript-14mi	How to build a Flash Title Notification with JavaScriptThe user s attention is important How do you call the attention of a user who is on another tab to your website In this article you will learn how to implement a flash title using LinkedIn sample that looks like this When a user is on another tab flash titles are useful for drawing their attention to the website as shown below You have probably seen a flash title on Facebook and some other websites when you have a new notification on their website So let s get started with building your own flash title This article is in two parts the HTML part and the JavaScript part The HTML PartCreate a new index html and add the HTML boilerplate that I ve created below lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset UTF gt lt meta http equiv X UA Compatible content IE edge gt lt meta name viewport content width device width initial scale gt lt title gt Document lt title gt lt head gt lt body gt lt SCRIPT gt lt script src index js gt lt script gt lt body gt lt html gt A version with LinkedIn Favicon lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset UTF gt lt meta http equiv X UA Compatible content IE edge gt lt meta name viewport content width device width initial scale gt lt title gt LinkedIn lt title gt lt link rel shortcut icon href id favicon ico gt lt link rel apple touch icon href gt lt link rel apple touch icon precomposed href gt lt link rel apple touch icon precomposed href sizes x gt lt link rel apple touch icon precomposed href sizes x gt lt head gt lt body gt lt script src index js gt lt script gt lt body gt lt html gt Ensure to add a title tag to your script because it is where the flashing notifications will be implemented The JavaScript partCreate an index js or whateverfilename js that you want We will create a function that will change the title tag and toggle between the current page title and the new notification messages that you want to toast to the user We will be making use of the document title to have access to the title tag text in the HTML document The code below will change the title of the page to the assigned string document title new notification The output of the above code Let s move on The Flash Title FunctionCreate a flashTitle function The function will accept two parameters the pageTitle and the newTitle then we will check if the current page title is the same as the pageTitle parameter if they are the same then we want to set the current page title to the newTitle parameter But if the current page title is not the same as the pageTitle parameter then we want to display the pageTitle The code below is the translation of the explanation given above function flashTitle pageTitle newTitle if document title pageTitle document title newTitle else document title pageTitle Calling the flashTitle function at this point will only display the pageTitle parameter you will need the toggle effect The Toggle EffectThe toggle effect adds the continuous swap of the page title and the new notification message the toggle effect will be implemented using the setInterval method The setInterval method is used to call a function continuously at a specified time in milliseconds and its syntax is shown belowsetInterval functionNameWithoutBracket NumberOfIntervalInMiliseconds We can call the flashTitle function to run at an interval of milliseconds setInterval flashTitle LinkedIn New Feeds LinkedIn The double quotation is required because we are passing arguments to the flashTitle function and setInterval does not require a parenthesis for a callback function The Flash Title The JavaScript Complete CodeBelow is the complete code snippet for the flash title JavaScript part function flashTitle pageTitle newTitle if document title pageTitle document title newTitle else document title pageTitle setInterval flashTitle LinkedIn New Feeds LinkedIn Using Ternary OperatorWe can replace the if statements with the ternary operator as well function flashTitle pageTitle newTitle document title pageTitle document title newTitle document title pageTitle setInterval flashTitle LinkedIn New Feeds LinkedIn Kudos you have successfully learned how to implement a flash title to a web application using JavaScript ConclusionFlash titles are very useful to alert the user of their new notifications when they are away on another website and in

海外TECH	DEV Community	React Basics | Part - 1	https://dev.to/elwinjyot/react-basics-part-1-473f	React Basics Part Heyyo fellow developers I planned on starting a React basics blog post series for all of you in the developer community who wants to get a taste of React Let s do this Level BeginnerRequirements A good understanding of JavaScript functions and ClassesWhat is React and why Simply speaking React is a JavaScript library which allows you to build fast and reusable web frontends Just like any other libraries in JavaScript let s say JQuery simplifies DOM manipulation in JavaScript or Lodash used to write more concise and maintainable JavaScript React can be simply imported into your JS file and can be used to render dynamic content into your browser Why should I use React Straight answer it s easy Let me explain Let s take an example of a project in which you are asked to build a simple e cart system You can add products to the cart remove them increase or decrease the quantity and also display the correct total amount too When implementing the old school methods of building web apps the data of every product in the cart can be stored in a database and we can do all the CRUD Create Read Update Delete functionalities on the data The catch is that if you need to display this updated data into the browser the whole page needs to be refreshed and then only the latest data can be presented React solved this by giving local variables to parts of a webpage and each part of the webpage has access to their local variables and React can update the data in the browser if the variable values are changed without refreshing the page This is just one example of React use case there is a lot of reasons why React is a great choice NOTEThis same functionality can be accomplished using regular DOM manipulation methods but React lays out all the backbone functionalities so you can just get started with your project right away Not only React but other techs such as Angular or Vue are also capable of this Before getting into the fun of codes Let s understand some theories of React React works in a component based structure Each part of a webpage can be broken down into small components and different components can be stacked together to form a webpage The advantage of this structure is that these components can be reused in other webpages too We can define variables for a component whose values can be inserted into HTML templates When these variable values are changed or updated React works to re render only the parts of the webpage that has the variable called These type of components are called stateful components in React Let us revisit the e cart example You can separate each product in a cart into different components and give each component some local variables such as quantity price and product name Now in this component we can write the HTML template and the css stylings only for this component We can call these variable inside the HTML to replace itself with their values First lets take a look at the component In the above image we can see a Product component The variable name in curly braces will be replaced by their respective values Let us say if we need to increase quantity we can just add one to the variable quantity and reassign the variable React will update the HTML without any refreshing There are types of components in React function based and class based components A function based component is not stateful by default but React hooks can be used to make it stateful we will be learning about hooks in later blogs Let us see an example of these components Function based componentsfunction App return lt h gt Hello world lt h gt Class based componentsclass App extends React Component render return lt h gt Hello world lt h gt You might have noticed the weird HTML tags in JavaScript code This is a special type of language extension for React components called JSX JSX is transpiled using babel and executed by React to display these HTML content onto the browser If we run this application we will able to see Hello world in the browser correctly rendered as an h element In the upcoming sections we will slowly build an e cart webapp while learning the magic of JavaScript and React Stay tuned Thanks for your time	2022-02-05 07:02:42
