Function.prototype.bind = function(){
    let context = [].shift.call(arguments)
    let self = this;
    let args = arguments;
    return function () {
        return self.apply(context,[...args,...arguments])
    }
}

let temp = Array.prototype.concat.bind([1,3,5],7,8,9)
console.log(temp(10,12));
