composition.js

var compose = function() {
    var funcs = arguments;
    return function() {
        var args = arguments;
        for (var i = funcs.length; i --> 0;) {
            args = [funcs[i].apply(this, args)];
        }
        return args[0];
    };
};


// example
const add1 = x => x + 1;
const double = x => 2 * x

const f = compose(double, add1);

console.log(f(100));
