Application

apply function allows to call several functions on the same arguments provided to apply.

It assumes that all functions have the same amount of arguments as the first one and that their type is the same as the first one accepts.

Its return type is the tuple of return types of all the functions provided to it.

import apply from 'fnts/apply';

apply(
    (a: number, b: number) => a + b,
    (a: number, b: number) => a - b,
    (a: number, b: number) => a / b,
    (a: number, b: number) => a * b,
)(3, 2); // [5, 1, 1.5, 6]
