Array.prototype.reduceLou = function( func, start = 0 ){

    let state = start;

    for(let i = 0; i < this.length; i++) {
        state = func(state, this[i]);
    }

    return state;

}

console.log([1, 2, 3].reduce((prev, item) => prev + item ))
console.log([1, 2, 3].reduceLou((prev, item) => prev + item ))
