How To Push The Array Of Data To Another Array Through Javascript Without Loop

I have an Json array like data {'alphaNumeric':[]}. Here I just want to push the another array [mentioned below] of objects to this Data with out loop concept. data{'numeric':[{'id

Solution 1:

One solution may be using the concat method. Which isn't really good as it creates a whole new array.

b.alphaNumeric = b.alphaNumeric.concat(a.numeric);

But there is a much better solution using push. It accepts more than just one element, but unfortunately not as an array. This can be however achieved using its apply method:

b.alphaNumeric.push.apply(b.alphaNumeric, a.numeric);

Also you can write your own method (I call it add) which will do this action for you:

Array.prototype.add = function (array) {
  this.push.apply(this, array);
  returnthis;
};

b.alphaNumeric.add(a.numeric);

Solution 2:

Use concat()

data.alphaNumeric.concat(data.numeric);

Solution 3:

.push() and .pop() are for adding and removing single elements in an array. The return value from .concat() is what you're looking for:

var newArr = oldArr.concat(extraArr);
