JavaScript 2

Course Code: JS2

Duration: 3 days

 
 

JavaScript 2 Course Overview

The JavaScript 2 course comprises sessions dealing with values and references, strict mode, arrays, scope, ES6, functional JavaScript, asynchronous JavaScript, reactive JavaScript and unit testing.

The delegate will learn about the inner workings of the JavaScript language to better enable them to write complex code and to troubleshoot.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Course Objectives

This course aims to provide the delegate with the knowledge to be able to interpret, write, and troubleshoot complex JavaScript code exploiting strict mode, closures, IIFEs, ES6, functional programming, asynchronous JavaScript, and reactive programming.

Who will the Course Benefit?

The JavaScript 2 course is designed for JavaScript developers who want to know more about the inner workings of the language so as to better equip themselves to write complex code and to troubleshoot. It is also intended to familiarise the delegates with modern approaches to coding with JavaScript including functional and reactive programming.

The course will also benefit those JavaScript developers who are familiar with JavaScript as it relates to ECMAScript version 5, and want to learn about what's new in ECMAScript version 6 (ES2015).

Skills Gained

The delegate will learn and acquire skills as follows:

  • Working with primitive and reference variables
  • Testing for equality
  • Coding in strict mode
  • Working with associative arrays
  • Determining and affecting the scope of a variable
  • Coding in ECMAScript version 6 (ES2015)
  • Functional programming
  • Coding asynchronously
  • Reactive programming using RxJS
  • Unit testing

Notes:
  • Course technical content is subject to change without notice.
  • Course content is structured as sessions, this does not strictly map to course timings. Concepts, content and practicals often span sessions.

Requirements

Delegates should be able to build JavaScript applications that exploit all fundamental elements of the language including variables and expressions, conditions and loops, functions, objects, arrays, the DOM, and event handling.

This knowledge can be obtained by attendance on the pre-requisite JavaScript 1 course.

Course Reviews

The course had good structure and progressively built on the knowledge we had obtained. The case study brought the content to life and allowed us to obtain feedback from Stuart as we were going along. Stuart has inspired me go away and learn more about JavaScript!

Finchley - August 2021


Excellent course run by Stuart Bailey, perfect code examples made the topics easier to understand, much better than death by PowerPoint.

Jamie - Junior Cloud Engineer - August 2021


This course was amazing really happy. I attended.

Okoye - Software Developer - August 2021


Super useful, thank you!

Rhysian - August 2021


A brilliant course - thanks Stuart. I've spent hours struggling with async and await, and you've given me a really clear understanding of how it works. One thing that may help is if you push the code to the shared drive more frequently, or updated in real time. I found coding along with you really helpful and enjoyable, but sometimes I didn't have chance to copy everything before you moved to a different file.

Richard - Senior Software Engineer - August 2021


Stuart has been a great training provider, very informative, good at answering difficult questions and understanding intentions.
