Discussion on: JS Functional Concepts: Pipe and Compose

Of course not, the main issue is not having tests.
Key in the discussion here being that coding in TypeScript is faster than vanilla JS + JSDoc + TS Pragma, you may never seen it this way but look:

/**
 * Sums two numbers
 * @param  {number} n1
 * @param  {number} n2
 * @returns {number}
 */
const sumTwoNumbers = (n1, n2) => n1+n2;

/** Sums two numbers */
const sumTwoNumbers = (n1: number, n2: number) => n1+n2;

As well as more reliable.
To get a similar reliability with JSDoc you need to ensure JSDoc is added and maintained through automatisms in the linter and run this step in the PR's pipeline, at least (i.e. ESLint plugin JSDoc) and it takes more to configure than what it takes to configure TS most of the time.

Keep in mind that using JSDoc and TSPragma you are just using one little piece of TS, which is about type definition and type reports (and it doesn't even cover it entirely).

If you just need those features, then add TS and just use those features 😂

Do you dislike interfaces? Fine, don't use them, if you are working in FP instead OOP, interfaces doesn't even make sense (in FP all functions are interfaces).

It is not mandatory to use everything from TS so don't stress it so hard 😁
