Function Composition

Implement a compose function that takes multiple functions and returns a new function that applies them right-to-left.

Requirements

• compose(f, g, h)(x) should equal f(g(h(x)))
• Should work with any number of functions
• With no functions, return the identity function

Example

const add1 = x => x + 1;
const double = x => x * 2;
compose(add1, double)(5); // 11 (double first: 10, then add1: 11)
