Furthermore, it is not type checking in the browser or type checking in Node.js. Type annotations isn’t an endorsement of a particular type system. Now that we understand what the proposal is, let’s consider what it isn’t. So instead of writing the JSDoc equivalent, imagine if JavaScript was happy with the following instead: const theAnswer: number = 42 The proposal allows for types to be directly expressed rather than be written as comments. This works but it took two lines of code instead of one. It’s already possible to write our code sample in valid JavaScript, expressing the types within JSDoc. Essentially, the thing to note is that JSDoc allows for storing type declarations in the context of JavaScript comments. I’ve written about how TypeScript and JSDoc connect before. Interestingly, it’s already possible to store types within JavaScript through a standard known as JSDoc. If you try and run it in a JavaScript engine, you’ll get an error because types are not part of JavaScript syntax. Consider the following piece of TypeScript: const theAnswer: number = 42 Īt present, this is not valid JavaScript. Type annotations (or “tomments,” as some have dubbed it) is a proposal that would allow for the inclusion of types in JavaScript code. As a regular (and longtime) TypeScript user, here’s a description of the proposal and some thoughts. Many of these people are from the TypeScript community - however, this proposal intentionally does not exist to benefit TypeScript alone.

The proposal is being worked on by Gil Tayar, Daniel Rosenwasser, Romulo Cintra, Rob Palmer, and others. The purpose of the proposal is to allow type annotations to be valid JavaScript syntax, albeit syntax that is ignored by JavaScript engines. Recently, a new ECMAScript proposal called type annotations (previously referred to as types as comments) was revealed.
