JavaScript is a scripting language that enables interactive and dynamic features on websites. It works alongside HTML and CSS to create engaging user experiences, such as interactive forms, animations, and responsive layouts. JavaScript is essential for developing modern web applications and ensuring seamless functionality across different devices and screen sizes.


JavaScript is a scripting language used to create interactive elements on websites, such as image sliders, pop-up notifications, and form validation. For example, when you click a button to submit a form and see an error message if you missed a required field, that’s JavaScript in action.
