1. What is JavaScript?
​JavaScript is a popular high-level programming language primarily used for developing
interactive web applications. It is supported by all modern web browsers and enables dynamic
and responsive behavior on web pages. JavaScript can be used for a wide range of purposes,
including form validation, interactivity, animations, and data manipulation.
2. JavaScript Syllabus Overview
To master JavaScript programming, it is essential to cover a comprehensive syllabus that
encompasses both fundamental and advanced topics. The following syllabus is designed to
provide a structured learning path:
