海外TECH	DEV Community	JSX: The Secret Sauce Behind React's Success	https://dev.to/bowen/jsx-the-secret-sauce-behind-reacts-success-2hhk	JSX The Secret Sauce Behind React x s SuccessReact is a popular JavaScript library for building user interfaces It was created by Facebook and released to the public in Since then it has gained widespread adoption in the tech industry and is used by many companies big and small to build web and mobile applications One of the reasons for React s popularity is its ability to create complex and dynamic user interfaces with ease React uses a syntax called JSX JavaScript XML allowing developers to write HTML like code within JavaScript making it easier to reason about the structure and behavior of their applications In this article we will delve into the details of JSX and explore how it makes React such a powerful tool for building dynamic and engaging user interfaces Pre requisitesTo follow along through this article you are required to have Basic knowledge of HTMLKnowledge in JavascriptBasic React skills IntroductionJSX is a syntax extension to Javascript and is used with React to describe how the user interface should look like This enables React to utilize declarative aspect of programmming You might find the word declarative a bit complex but don t worry we are going to cover it in this article To understand the role of JSX in React we will take a look at how we create HTML elements in plain JavaScript then look at how they are created in React We will cover Imperative vs Declarative ProgrammingCreating HTML elements in Vanilla JavaScriptCreating HTML elements in ReactNesting in JSX Imperative vs Declarative ProgrammingSuppose you wish for someone to prepare a cake for breakfast You have two options Firstly you can simply request the baker to bake assuming they know how to do it and omit giving any instructions on the baking process Alternatively you can still request the cake but also provide the baker with instructions on how to go about the baking process Imperative programming is a software development paradigm where functions are implicitly coded in every step required to solve a problem while declarative programming is a paradigm which utilizes abstraction of the control flow behind how a particular solution is achieved Declarative describes what you want to do not how you want to do it The idea about giving instructions on how something should be done explains the imperative aspect of programming while the other explains declarative aspect of programming Creating HTML elements in Vanilla JavaScriptBefore we get into how JSX is used in React applications we will first get to understand how it is done in pure JavaScript Create an index html file and paste the code below and open it in your browser 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 h gt The Document Object Model lt h gt lt h gt The createElement Method lt h gt lt p gt Create a p element and append it to the div with id myDiv lt p gt lt div id myDiv style padding px background color paleturquoise gt lt h gt My Div lt h gt lt div gt lt script gt create HTML element const paragraph document createElement p paragraph innerHTML Created a paragraph using JS append to the myDiv div document getElementById myDiv appendChild paragraph lt script gt lt body gt lt html gt createElement creates the HTML element specified by the tagName which is its parameter appendChild on the other hand adds the node or rather element created to the end of the list of children of the specified parent myDiv in our case node If you understood the two programming paradigms above you will categorize this as an imperative programming because we are implicitly giving instructions on how it should be done Creating HTML elements in ReactIn React JSX is a syntax extension recommended to describe how the user interface should look like To further understand how this happens we are going to create a simple React application by pasting the code below on our terminal npx create react app jsx democd jsx demonpm startYou can edit the src App js file by pasting the code belowimport React from react function App const hTitle lt h className htitle gt JSX in a nutshell lt h gt return hTitle export default AppIn JavaScript we cannot assign HTML elements to values as shown above however in React JSX gives us the power to do that Since almost everything in JavaScript is an object the hTitle is also an object and we can log it to see what it contains Just below the hTitle assignment you can add console log hTitle type h props className htitle children JSX in a nutshell The above is a cleaner view of the result which you are seeing on the console after inspecting your application This representation is what is known as a React Element which represents the final HTML output as a plain object Each node in the JSX is a plain object describing a component instance or a DOM node and its desired properties props The two main attributes of the React Element is the type which defines the type of node and the props which is the properties a component receives Once the React Elements for all components are established React converts it into actual HTML DOM elements Nesting in JSXAdditionally nesting can be done in JSX just as it can be done in HTML One key concern when nesting JSX nodes is to ensure that there always has to be a parent node Consider a bad JSX implementation const pageContent lt h className htitle gt JSX in a nutshell lt h gt lt p gt It s amazing how JSX works lt p gt To address the error which will be generated by the code above we can wrap it with a div as shown below const pageContent lt div className page content gt lt h className htitle gt JSX in a nutshell lt h gt lt p gt It s amazing how JSX works lt p gt lt div gt We can also console pageContent object and see what it contains type div props children type h props className htitle children JSX in a nutshell type p props children It s amazing how JSX works className page content children is an array of two objects each representing a specific JSX node Thid array will grow depending on the number of children a parent node has The ability of React to convert these objects into HTML elements without us programmers to implicitly do it make React declarative ConclusionMany React developers myself included lack an understanding of JSX and its role in React However after reading this article we gained a straightforward understanding of JSX and how it enhances React as a powerful library If you
