Beginner to intermediate content levelBeginner to intermediate

Build and maintain large web applications

TypeScript is an open source superset of JavaScript that you can use anywhere you can use JavaScript. It includes static types and helps you build applications that are easier to maintain and contain fewer bugs.

Join expert Brice Wilson to learn how to install TypeScript, run the compiler, and use all of the basic features of the language. Along the way, you’ll explore the relationship between JavaScript and TypeScript, the benefits of static typing in client-side applications, the syntax for creating and using generics, and more.

What you’ll learn and how you can apply it

By the end of this live online course, you’ll understand:

  • The relationship between JavaScript and TypeScript
  • The benefits of using TypeScript over JavaScript
  • What a structural type system is and how it applies to TypeScript
  • The benefits of using generics in your TypeScript applications

And you’ll be able to:

  • Install and run the TypeScript compiler
  • Use a tsconfig.json file to configure a TypeScript project
  • Apply type annotations to variables and functions
  • Create your own types with interfaces and classes
  • Use generics to create code that’s more reusable

This live event is for you because...

  • You’re a web developer curious about TypeScript.
  • You’re working on medium to large web applications and want more maintainable code.
  • You want to create browser and Node.js applications with fewer bugs.
  • You’ve used other strongly typed languages and want to get started in web development.

Prerequisites
