Who it’s for
This course is designed for developers who are ready to go beyond the basics and build real, structured JavaScript applications. It is a strong fit if you are new to JavaScript but already comfortable with HTML, CSS, and basic programming concepts, and want to develop the skills to work on live projects straight away.
It is equally well suited to developers returning to JavaScript after a break who want to update their knowledge with modern syntax, object oriented and functional programming techniques, and asynchronous patterns. If you are working in a technical role and want to deepen your JavaScript capability or you are preparing to move into framework development with React, Angular, or Node.js, this four day course gives you the structured foundation to do that with confidence.

Entry requirements
Before joining this course, you should be comfortable with the core principles of HTML and CSS and have some prior experience with programming concepts such as variables, functions, and basic logic. You do not need to be an expert, but a working familiarity with how web pages are structured and styled will help you get the most out of the four days.
If you are starting from scratch or feel you need a stronger foundation before diving in, we recommend completing our Introduction to Programming — JavaScript and Introduction to HTML and CSS courses first. These will ensure you arrive with the right level of knowledge and are ready to progress at pace from day one.

Syllabus – key points
This course is structured across four focused modules that take you from the core building blocks of JavaScript through to advanced programming techniques and real world application development. Each module builds on the last, giving you a progressive and practical learning experience that equips you with skills you can apply directly to your own projects from day one.
- Working with Variables and Data Types Variables, constants and dynamic typing · Primitive types including strings and numbers · Arrays and objects · Type conversion and coercion · Data manipulation and transformation · Real world data structures
- Functions, Scope and Programme Flow Conditional logic and loops · Error handling and debugging · Function declarations, expressions and arrow functions · Default parameters · Scope and the scope chain · Closures · Modular and reusable code
- Programming Approaches: Object Oriented and Functional Classes, constructors and inheritance · Object oriented principles · Pure functions and immutability · Higher order functions · Functional programming techniques · Scalable project organisation
- DOM Interaction, Events and Asynchronous Tasks Accessing and updating the DOM · Event handling and interactive interfaces · Callbacks and background tasks · Promises and async/await · Asynchronous programming patterns · Real time data processing
