Dynamic tag name in React JSX

When working with React JSX, you may come across situations where you need to dynamically render different HTML tags based on certain conditions or data. In this blog post, we will explore different approaches to achieve this in React.

1. Using a conditional statement

One way to render dynamic tag names in React JSX is by using a conditional statement. You can use an if-else statement or a ternary operator to conditionally render different tags.

Here’s an example:

{`import React from 'react';

function DynamicTag({ tagName, text }) {
  if (tagName === 'h1') {
    return 
{text}
;
  } else if (tagName === 'h2') {
    return 
{text}
;
  } else {
    return {text}
;
  }
}

export default DynamicTag;`}

In this example, the component DynamicTag takes two props: tagName and text. Based on the value of tagName, it conditionally renders different HTML tags.

2. Using a component variable

Another approach is to use a component variable to dynamically render the desired tag name. This can be achieved by assigning the desired tag name to a variable and then using that variable in JSX.

Here’s an example:

{`import React from 'react';

function DynamicTag({ tagName, text }) {
  const Tag = tagName;

  return {text};
}

export default DynamicTag;`}

In this example, the component DynamicTag assigns the value of tagName to the variable Tag. The variable Tag is then used in JSX to render the desired tag name.

3. Using the createElement method

React provides a createElement method that can be used to create React elements dynamically. This method takes three arguments: the tag name, props, and children.

Here’s an example:

{`import React from 'react';

function DynamicTag({ tagName, text }) {
  const element = React.createElement(tagName, null, text);

  return element;
}

export default DynamicTag;`}

In this example, the component DynamicTag uses the createElement method to create a React element dynamically. The tagName is passed as the first argument, null is passed as the second argument for props (since we don’t have any props in this example), and text is passed as the third argument for children.

These are three different approaches to dynamically render tag names in React JSX. Choose the one that best suits your use case and enjoy the flexibility of dynamic rendering in your React components!

That’s all for this blog post. Happy coding!
