The Complete Syllabus for learning Javascript

Javascript is a popular General Purpose Programming Language. It is predominantly used in web development. It can be used in frontend as well as backend. Learning Javascript is a key point in excelling at web development.

In this blog post, we show you the full syllabus for learning Javascript from beginner to Expert level.

Prerequisites

The only prerequisite to learning Javascript is HTML. A basic understanding of HTML tags & document structure is enough to start learning Javascript. Additionally, you may also learn CSS before starting Javascript.
