The push() method of Array instances adds the specified elements to the end of an array and returns the new length of the array.
Parameters
element1, …, elementN\t The element(s) to add to the end of the array.
Return value
The new length property of the object upon which the method was called.
The push() method appends values to an array.
Array.prototype.unshift() has similar behavior to push(), but applied to the start of an array.
The push() method is a mutating method. It changes the length and the content of this. In case you want the value of this to be the same, but return a new array with elements appended to the end, you can use arr.concat([element0, element1, /* ... ,*/ elementN]) instead. Notice that the elements are wrapped in an extra array — otherwise, if the element is an array itself, it would be spread instead of pushed as a single element due to the behavior of concat().
The push() method is generic. It only expects the this value to have a length property and integer-keyed properties. Although strings are also array-like, this method is not suitable to be applied on them, as strings are immutable.
Adding elements to an array
The following code creates the sports array containing two elements, then appends two elements to it. The total variable contains the new length of the array.
Merging two arrays
This example uses spread syntax to push all elements from a second array into the first one. Merging two arrays can also be done with the concat() method.
Calling push() on non-array objects
The push() method reads the length property of this. It then sets each index of this starting at length with the arguments passed to push(). Finally, it sets the length to the previous length plus the number of pushed elements.
