Core JavaScript
Course Code: JSC
Duration: 2 days
Core JavaScript 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 fundamental knowledge and skills necessary to code in JavaScript, but with special attention on the front-end. Delegates will learn about variables and data types, functions, program flow, the DOM, event handling, and Web APIs.
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 basic JavaScript code that exploits variables, functions, conditional and iterative statements, and objects. Delegates should also be able to exploit their knowledge of the DOM, event handling, and Web APIs to make web pages dynamic and interactive.
Who will the Course Benefit?
The 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. 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
