TypeScript for Beginners

Video description

Simplify your code by applying the fundamentals of TypeScript and develop the skills needed to work with Angular JS

About This Video

  • Get to grips with the basics of TypeScript and understand what it offers
  • Learn ways to create functions that take optional, default, and variable number of arguments
  • Gain insights into the key object-oriented principles used in TypeScript

In Detail

TypeScript makes the life of developers easy by simplifying code. It follows programming conventions that make the project easy to understand even for someone from the distributed team who has no prior knowledge. This makes it popular among developers who use JavaScript frameworks, AngularJS, and Vue.js. This course will show you how TypeScript provides structures such as Java and Python to make coding easy.

Starting with an introduction to TypeScript, the course highlights why you should use it. Once you've set up the development environment, you'll write your first program using Visual Studio Code to understand variables and data types in TypeScript. Next, you'll become familiar with operators and learn how to control the flow of your application with flow control statements such as If, Else, Switch, and While Loop.

As you progress, you'll develop efficient TypeScript applications using functions, interfaces, classes, and inheritance. You'll also learn how to use different access modifiers and encapsulate classes and objects. Finally, you find out how you can use typecasting to convert one data type to another and use function modules.

By the end of this course, you'll be ready to start your career as a TypeScript developer and easily learn newer versions of JavaScript such as ES 6 or 7 in the future.

Who this book is for

Whether you are a JavaScript developer who wants to learn and master the fundamentals of TypeScript or a developer with a background in any OOP language looking to learn AngularJS, this course is for you. Basic knowledge of JavaScript is necessary to get started with this course.
