Overview

TypeScript is a superset of JavaScript used for building complex and robust web applications. Where JavaScript code is prone to failures at runtime, TypeScript, thanks to its static typing, flags errors at compile time. TypeScript builds upon ES6 with features such as interfaces, access modifiers, generics, and decorators, and may be transpiled into any ECMA version from ES3 through ESNEXT. TypeScript is the default language of the Angular framework and is supported by both React and Vue.

This course covers all of the key TypeScript features including static typing, classes, interfaces, generics, iterators and generators, modules and namespaces, JSX, and decorators.

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

Objectives

The delegate will learn and acquire skills as follows:

  • Declare and initialise statically-typed variables using let and const
  • Assign values to variables efficiently using destructuring and the spread operator
  • Declare statically typed functions exploiting optional, default, and rest parameters
  • Build classes exploiting the OO principles of encapsulation, inheritance, and abstraction
  • Use interfaces to define contracts within the code
  • Handle generic types and build generic classes
  • Build custom iterators and generators
  • Split code over multiple files using modules and/or namespaces
  • Use JSX to simplify the dynamic generation of HTML
  • Build and deploy decorators to add functionality to existing classes, methods, etc.

Target Audience

This course is designed for JavaScript developers who are required to build or maintain applications written in TypeScript.
