JavaScript Syllabus | Advanced JavaScript Topics

JavaScript is a compact, object-based computer programming language for developing client and server internet applications.

We commonly use JavaScript language in web development to create interactive effects within the web browser. Brendan Eich of Netscape originally developed JavaScript language.

JavaScript is an open source, script-based programming language where the source code is processed by the client’s web browser rather than on the web server.

Here, we have designed the complete JavaScript syllabus for comprehensive study. This syllabus contains full industrial JavaScript topics to learn the JavaScript from basic to advanced level. This syllabus will cover ES6+ features, core concepts, modern syntax, and advanced topics up to ES2023 (ECMAScript 2023).

IT professionals, freshers, and engineering students from Computer science/Information Technology professional degrees can learn complete JavaScript scripting language based on industry syllabus.

Professionals from the IT industry who are currently working in other programming languages and want to switch over JavaScript can use this syllabus to enhance their knowledge of JavaScript.

We divide the complete JavaScript syllabus into 24 chapters. The following chapter name, with a brief description, is given below:
