How to Change Button Color in React Js
React Js Change Color Button on Click: To change a button's color in React.js onClick, you can create a state variable to track the button's color and use the useState hook. Initially, set the color to its default value. When the button is clicked, use the onClick event handler to update the state variable with a new color. Then, apply this color to the button's style using inline CSS or a CSS class with conditional rendering. This way, when the button is clicked, React re-renders the component with the updated color, giving the appearance of a color change.

How to Change Background Color when Click on Button in React Js
This Reactjs code creates a button that changes its color when clicked. The button's color is managed using the state variable "isClick," initialized as true (red). When the button is clicked, the "toggleColor" function is called, which toggles the state value between true and false. The button's inline style uses a ternary operator to set the background color based on the "isClick" state (green when true, cyan when false).

How does it enable the change of a button's background color upon clicking?
This React.js code snippet creates a button that changes its background color on click using CSS toggling. It uses the useState hook to manage a state variable isButtonActive, which tracks whether the button is active. The button's class name is conditionally set based on the isButtonActive state, adding the class 'active-button' when the button is active. CSS styles associated with 'active-button' can be defined to change the button's background color. When the button is clicked, setIsButtonActive toggles the state, causing the button's class to change and alter its background color, providing a visual indication of its state.
