Intro to JavaScript
- JavaScript is a high-level programming language that is used to create dynamic and interactive web pages. It is a versatile language that can be used for a variety of purposes, from simple animations to complex web applications. JavaScript is a client-side language, which means it runs on the user's computer. This allows for faster processing and reduces server load.
- JavaScript is essential for web development because it allows developers to create engaging and interactive websites. With JavaScript, you can create dynamic content that responds to user input and changes based on user actions. JavaScript can also be used for form validation, creating animations, and much more.
Why JavaScript is Essential for Web Development
