How can I replace elements in array with elements of another array?
For example, I have two arrays:
xxxxxxxxxx1
var array1 = [1, 2, 3, 4, 5];2
var array2 = ['a', 'b', 'c'];I want to replace all the elements from index 0 in array1 with the elements of array2.
The result should be:
xxxxxxxxxx1
[ 'a', 'b', 'c', 4, 5 ]How can I do that?

You can use splice() method to do so.
Practical example
xxxxxxxxxx1
var array1 = [1, 2, 3, 4, 5];2
var array2 = ['a', 'b', 'c'];3
4
Array.prototype.splice.apply(array1, [0, array2.length].concat(array2));5
6
console.log(array1); // [ 'a', 'b', 'c', 4, 5 ]
