How to call a function from ...spread?

The question is absolutely incomprehensible, but I'll try play the guessing game:

const f = (...callbacks) => { // spread collects arguments into an array, // so you can work with them as an array callbacks.forEach((callback) => callback()); } f( () => console.log(1), () => console.log(2), () => console.log(42), );

If you pass multiple variables, and collect and spread, you get an array of variables, so here, only the elements of the array will function.

Why not do an array of functions?

function f (callbacks) { for (let i = 0; i < callbacks.length; i++) { callbacks[i](); } } f ( [ _ => console.log(0), _ => console.log(1), _ => console.log(10), ] );
