Implicitly create a tuple in Typescript

Issue

Is there a way without type hinting to create a tuple in Typescript.

If I simply do

const tuple = [1, 2];

the type of Tuple number[]

The closest I can get to a oneliner is

const tuple: [number, number] = [1, 2];

Am I missing something, or is this the only way?

Solution

As of TypeScript 3.4, you can add simply as const at the end.

const tuple = [1, 2] as const;

Full credit to @bela53's answer, which has a better example and link to TS playground.
