In this blog post, we take a first look at the ECMAScript proposal “Record & Tuple” (by Robin Ricard and Rick Button). This proposal adds two kinds of compound primitive values to JavaScript:

• Records, immutable compared-by-value versions of plain objects
• Tuples, immutable compared-by-value versions of Arrays

This blog post describes how to create web apps via TypeScript and webpack. We will only be using the DOM API, not a particular frontend framework. The repository ts-demo-webpack with the files can be downloaded from GitHub.

This blog post gives the bird’s eye view of how TypeScript works: What is the structure of a typical TypeScript project? What is compiled and how? How can we use IDEs to write TypeScript?

This post is meant to be read before learning how to write TypeScript code (material for doing that is listed at the end).

This blog post gives an overview of strategies for migrating code bases from JavaScript to TypeScript. It also mentions material for further reading.

This blog post describes how to use TypeScript to create npm packages with CommonJS modules. All the artifacts that are shown can be downloaded via the GitHub repository ts-demo-npm-cjs (I deliberately have not published it to npm).

In this blog post, we explore classes as values:

• What types should we use for such values?
• What are the use cases for these types?

This blog post explores static typing for functions in TypeScript.

In this blog post, we examine how class definitions work in TypeScript:

• First, we take a quick look at the features of class definitions in plain JavaScript.
• Then we explore what additions TypeScript brings to the table.

What are types in TypeScript? This blog post describes two perspectives that help with understanding them.

In this blog post, we examine how Arrays can be typed in TypeScript.
