How to Enable HTML in JavaScript Using Visual Studio Code?

Estimated read time 2 min read

HTML can be enabled in JavaScript files in Visual Studio Code by using embedded JavaScript (JSX) syntax or by writing HTML in a string and rendering it with JavaScript code.

Here’s an example of using JSX to embed HTML in JavaScript:

import React from 'react';

function App() {
  return (
    <div>
      <h1>Hello, World!</h1>
    </div>
  );
}

export default App;

In this example, the HTML is embedded directly in the JavaScript code, inside the return statement. The syntax is similar to HTML, but it is surrounded by angle brackets < and >. The code uses the React library to render the HTML, but other libraries like Vue.js and Angular.js can be used as well.

Note that this syntax is specific to JSX and requires a special setup in Visual Studio Code, including installing the React library and the necessary tools and extensions.

Here’s an example of using JavaScript to render HTML:

const h1 = '<h1>Hello, World!</h1>';

document.body.innerHTML = h1;

In this example, the HTML is stored in a string h1. The code then sets the innerHTML property of the document.body object to the value of the string. This updates the HTML of the page to display the contents of the string.

Note that this method of rendering HTML is considered to be less safe and less performant than using JSX or a modern front-end framework, and it should be used with caution. It is recommended to encode the HTML string to prevent cross-site scripting (XSS) attacks.
