JavaScript Developer
Course Code: JSD
Duration: 4 days
JavaScript Developer Course Overview
JavaScript is one of the most popular and commonly used programming languages today. Not only is it the language of the web and front-end frameworks like Angular and React, but it can now be used to build anything (front-end, back-end, or otherwise) thanks to runtimes like NodeJS.
This course is designed to provide delegates with the knowledge and skills necessary to build modern JavaScript apps. It further serves to set the delegates on course to dive into one of the many JavaScript frameworks. Delegates will learn about everything from variables, functions, and program flow, to functional and asynchronous programming, and managed apps.
Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
NB: This course assumes ES6 as the baseline specification for JavaScript. This is because ES6 is now widely supported.
Course Objectives
This course aims to provide delegates with the skills and knowledge necessary to write core JavaScript code, exploit an understanding of the DOM and event handling to make web pages dynamic and interactive, and to build modern, managed JavaScript applications that exploit modern syntax. Delegates should be able to devise object-oriented and functional solutions to problems, and deal with asynchronous tasks such as IO.
Who will the Course Benefit?
The JavaScript Developer course is aimed at those who are new or have had little exposure to JavaScript, and who will be responsible for building or maintaining JavaScript apps and want to go beyond the fundamentals. It may also be of value to those who wish to refresh/renew their knowledge of JavaScript after some time away from it.
Skills Gained
The delegate will learn and acquire skills as follows:
- Build and deploy a simple web app
- Make use of built-in data types for managing data
- Exploit functions to compartmentalise and re-use code
- Manage program flow via conditions, loops, and error handling
- Manipulate the DOM
- Respond to the user via event handling
- Make use of Web APIs such as Date, JSON, and LocalStorage
- Make use of modern syntax and operators such as destructuring and spread etc.
- Grasp the complexity of JS scope including closures and IIFEs
- Encapsulate data and behaviour by exploiting object-oriented features
- Exploit functional techniques such as pure and higher-order functions etc.
- Manage asynchronous tasks via callbacks, Promises, and async await
- Build a managed app that exploits modules and tooling
- Code tests to verify behaviour

Requirements
Delegates should have some previous programming experience or at least be familiar with programming concepts. Delegates should also be familiar with HTML and CSS. This knowledge can be gained by attendance on the pre-requisite Introduction to Programming - JavaScript and Modern, Responsive Websites with HTML & CSS courses.

Course Reviews
Stuart was an excellence trainer, the content was very well explained and broken down with adequate time for practical exercises.
Dheep - Front end Developer - Government - June 2024
The course was amazing! Until now I have been doing online courses and going off to discord servers to ask questions but having someone in person helps a lot! Stuart's been amazing, who explained things with depth to really understand what JS does in the backend, which other tutorials fail to explain.
