Answer:avaScript is a scripting language used to make web pages interactive. It works with HTML and CSS to create dynamic content like animations, form validations, and user interactions. It’s important because it runs directly in the browser, allowing developers to create responsive and interactive web applications. ✅ Question 2 What is the difference between == and === in JavaScript?
