Using JavaScript, adding an element to an array results in the array returning a value of 1

When I try to push a string into an array and then return the array, I am getting unexpected result of "1". Upon closer inspection, it seems that the array is being successfully created but before returning it, only "1" is being returned. Here is the snippet of my code:

Using the arr.push() method will return the new length of the array.

If you start with an empty array and push a value using this.alertMessage, the length of the array will be 1 (arr.length).
