How Can I Dynamically Add and Manage Class Names in JSX?

Dynamically Enhancing Class Names in JSX

In JSX, enhancing class names dynamically can be challenging. One common requirement is to add a conditional class based on a state or prop. Here's how you can achieve this:

Option 1: JavaScript Concatenation

<div className={'wrapper searchDiv ' + this.state.something}>
  ...
</div>

This method leverages JavaScript concatenation to add the dynamic class to the existing class list.

Option 2: String Template Literals

<div className={`wrapper searchDiv ${this.state.something}`}>
  ...
</div>

String template literals (backticks) provide a cleaner syntax for constructing dynamic class names. They allow you to embed expressions within strings using ${}.

Notes:

• Remember, JSX attributes are treated as JavaScript code, so you can execute JavaScript within curly brackets.
• However, combining JSX strings and curly brackets within attributes is not supported.
• Both JavaScript concatenation and string template literals offer viable solutions for dynamic class name manipulation in JSX.
