TypeScript Course Overview TypeScript is a static type checker for JavaScript. Where JavaScript code is prone to failures at runtime,TypeScript flags errors at compile time. Angular applications are written in TypeScript by default,and TypeScript is supported by both React and Vue. This course deals with all of the core TypeScript features including type inference,explicit typing,primitive types,object types,union types,aliases,interfaces,literal types,narrowing,function types,extending types,generics,type manipulation,and classes. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
TARGET AUDIENCE:
Who will the Course Benefit? This course is designed for JavaScript developers who are required to build or maintain applications written in TypeScript.
COURSE PREREQUISITES:
Requirements Delegates attending this course should be familiar with/able to write JavaScript code up to and including features detailed in ES6. This can be achieved via attendance on our JavaScript Developer course.

COURSE OBJECTIVE:
Course Objectives This course aims to enable the delegate to build web applications using TypeScript. That is,the delegate ought to be able to write using TypeScript,that which they previously wrote using JavaScript,and in so doing produce code which is better and more robust.
