Dynamic tag name in React JSX

🌟 Dynamic Tag Name in React JSX: A Guide

Are you tired of hardcoding your React component's HTML heading tags? 😫 Do you want to dynamically set the heading level based on a prop? 🏗️ Look no further, my friend! In this blog post, I'll show you how to solve this common issue 🤓 and empower you to level up your React game! 🚀

The Problem 🤔

The challenge lies in dynamically setting the tag name for HTML headings in a React component. Traditionally, you might try something like this 👇:

<h{this.props.level}>Hello</h{this.props.level}>

And you may expect to see the output 👇:

<h1>Hello</h1>

But alas, this approach does not work as expected! 😢

The Solution 💡

Fear not, for there's a simple solution to achieve the desired dynamic heading tag in React JSX! 🎉

To overcome this obstacle, you can utilize the React.createElement() function, which allows you to create custom React elements with dynamic tag names. Here's how it looks in action 👇:

React.createElement(`h${this.props.level}`, null, 'Hello')

This line of code dynamically generates the desired HTML heading tag using the level prop. Voila! 😎

Implementation Example 🚀

Now, let's put theory into practice! Suppose you have a Header component that accepts a level prop to determine the heading's level. Here's an example implementation to give you a clear picture 👇:

import React from 'react';

const Header = (props) => {
  const Tag = `h${props.level}`;

  return React.createElement(Tag, null, 'Hello');
};

export default Header;

In this implementation, we create a variable Tag that dynamically holds the appropriate HTML heading tag based on the received level prop. We then use React.createElement() to generate the desired heading tag. Easy-peasy, right? 😉✨

Your Turn! 🚀📢

Now that you've learned this awesome trick, it's time to put it to use! Try implementing a React component that dynamically changes the heading tag based on user input or any other condition. Get creative! 🎉
