Brainstorming -- using reduce method to reconstruct concat function

utilize reduce Method refactoring concat function

Array.prototype.myconcat = function () {
    
    var res = this;
    var a = Array.prototype.slice.apply(arguments)
    return a.reduce(function(p,e){
    
    	//*****************************************
        if(Array.isArray(e)){
    
            var x = e.reduce(function(v,t){
    
                v.push(t)
                return v
            },p)
            return x
        }else{
    
            p.push(e)
            return p
        }
        //*******************************************
    },res)
}

var i = [1, 2, 3, 4]
console.log(i.myconcat([34, 5, 6], 78, [25, 34],[23,76,[1,2,3]]));
//[1, 2, 3, 4, 34, 5, 6, 78, 25, 34, 23, 76, Array(3)]

a = [1,2,3]
b = [4,5,6]

var x = a.reduce(function(v,t){
    
	// You can't go back here return v.push(t)
	v.push(t)
	return v
},b)
console.log(x);
//
