Introduction to JavaScript
JavaScript is a versatile and essential programming language for web development. It allows you to add interactivity, manipulate the DOM (Document Object Model), and create dynamic web applications. Before diving into the course content, let’s address some common questions:
What is JavaScript?
JavaScript is a high-level, dynamically-typed, and interpreted programming language used primarily for web development. It was originally developed by Netscape and is now supported by all major web browsers.
Why Learn JavaScript?
Learning JavaScript is crucial for web development. It enables you to create interactive and responsive websites and is a fundamental skill for front-end and full-stack developers.
Is JavaScript the Same as Java?
No, JavaScript and Java are not the same. While they share a similar name, they are entirely different languages with distinct purposes and syntax.
Prerequisites
To follow this course, you should have a basic understanding of HTML and CSS. If you’re new to web development, consider starting with an HTML and CSS course before diving into JavaScript.
