How to push an array into the object in JavaScript ?

In order to push an array into the object in JavaScript, we need to utilize the push() function. With the help of Array push function this task is so much easy to achieve. 

push() function: The array push() function adds one or more values to the end of the array and returns the new length. This method changes the length of the array. But here we will use this function to push the whole array into an object.

arr.push(element1[, ...[, elementN]])

    arrayTwo: []
};

// Array to be inserted
var arraynew = ['Geeks', 'for', 'Geeks'];

// Push an array to object
