TypeScript

T

he TypeScript course comprises sessions dealing with setting up TypeScript, adding to a project in either React or Angular, static types, access modifiers, classes, testing and debugging, and exporting code in modules.

The delegate will learn how to use TypeScript to build compositional applications through use of inheritance and interfaces.

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:

• Installing TypeScript
• Using TypeScript developer tools
• Preparing a TypeScript project:
  
  • Standalone with Webpack
  • In the Angular CLI
  • In create-react-app
• Using types, variables, functions
• Using classes and interfaces
• Using arrays, tuples, and enums
• Understanding and applying generics
• Creating namespaces and modules
• Compiling and running TypeScript
• Testing TypeScript

This course aims to provide the delegate with the knowledge to be able to add type safety and a compile-time stage, along with extra linting and debugging tools, using this recently-developed superset of the JavaScript language.

Delegates attending this course should be able to define general programming concepts including compilation and execution, variables, arrays, sequence, selection and iteration, navigate the filesystem (on the command line ideally), edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming course.

Delegates should in addition be conversant with modern ES6 JavaScript and ideally already using a JavaScript framework. This minimum level of knowledge can be obtained by attendance on the pre-requisite JavaScript 1 course.
