✅ Question 1 What is JavaScript and why is it important?
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?
Answer:In JavaScript, == is the loose equality operator, which compares two values after performing type coercion, meaning it converts the operands to the same type before comparing. On the other hand, === is the strict equality operator, which compares both the values and their data types without any type conversion.
