How to concatenate all elements of an array in another without using loop? [duplicate]

Question

I have this array:

var arrayPpal = [];

with this question I want to know how I can add the elements of other arrays to arrayPpal on the same level without having to perform cycles(without using cycle for, while.) or something like that.

var array1 = [1,2,3,4,5,6,7]; var array2 = [8,9,10];

the output should be:

arrayPpal = [1,2,3,4,5,6,7,8,9,10];

@PrerakSola I tried this Array.prototype.push.apply(); but I want know if there is a best way. in my real project this causes a rare problem.. — unusuario

Just use concat method. let arrayPal=array1.concat(array2) — Mihai Alexandru-Ionut

Use the concat method.

var arrayPpal=[]; var array1 = [1,2,3,4,5,6,7]; var array2 = [8,9,10]; arrayPpal = array1.concat(array2); alert(arrayPpal);
