Private Course: Click Here
The JavaScript 2 course comprises sessions dealing with values and references, strict mode, arrays, scope, objects, asynchronous JavaScript, unit testing and ECMAScript version 6.

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.

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
• Making changes to a constructor function’s prototype
• Determining an object’s prototype chain
• Exploiting inheritance and polymorphism
• Encapsulating a class using the Revealing Module pattern
• Declaring a static class using the Singleton pattern
• Coding asynchronously
• Unit testing
• Coding in ECMAScript version 6 (ES2015)

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.

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).

Entry 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.
