TypeScript Philosophy

Explore the fundamental philosophy and design goals of TypeScript. Understand how it aims to identify runtime errors, support large codebases, produce clean JavaScript output, and remain compatible with current and future ECMAScript standards. This lesson helps you grasp why TypeScript enhances developer productivity without changing JavaScript's core behavior.

We'll cover the following...

TypeScript has well-documented design goals that inspire developers who use it to follow its overarching philosophy.

The main point is to identify the construct that will produce a runtime error.

Secondly, TypeScript’s goal is to provide a structuring mechanism that can scale to a large codebase. JavaScript can be difficult to maintain with a large number of different developers and a substantive amount of code. This second goal embraces the first one which allows modification and being notified of potential issues as quickly as possible. Types also self-document the code and conscribed potential values to specific variables.

The third goal is to not impose overhead on the produced ...
