React Js conditionally applying className
React Js conditionally applying className:In React.js, conditional application of classNames can be achieved by using JavaScript's conditional (ternary) operator or logical AND (&&) operator within JSX.
By evaluating a condition, you can dynamically assign a className to a React element. For example, you can use {condition ? "classA" : "classB"} to apply classA when the condition is true and classB when it's false.
This allows for dynamic styling based on different states or props.

How can React.js be used to conditionally apply classNames to elements?
In this example, a React component named "App" is created. It uses the useState hook to define a state variable called "isActive" with an initial value of true.
Inside the JSX code, a div element is rendered with the className 'container'. Within this div, there is another div element with a className that is conditionally set based on the value of "isActive".
If "isActive" is true, the className will be 'active', otherwise, it will be 'inactive'. This allows for conditional rendering of CSS styles based on the state of the component.
