Ch-2 JSX/ES6
Computer Science student at Chandigarh University.
While surfing around the internet about react, everyone would have come across the terms like JSX, ES5, ES6 etc. These opaque acronyms can be a little confusing.
ES5(where ES stands for ECMAScript) is basically "regular JavaScript", where the numeric value stands for n^th update.
ES6 is a new version of JavaScript that adds some nice syntactical and functional additions.
Render
All React components have a render function that specifies what the HTML output of our React component will be. JSX is a React eXtension that allows us to write JavaScript code that looks like HTML.
The following code uses a React component that renders an h1 HTML tag. JSX allows us to declare this element in a manner that closely resembles HTML.
The render( ) function in the HelloWorld component looks like it's returning HTML, but this is actually JSX. The JSX is translated to regular JavaScript at runtime.
