The push() Function is used to insert new values at the end of the Array.
Let us say, we have a Array that contains three names, Mohan, Kriti and Salim. And we want to insert a new name Nikhil at the last of the Array.
<html> <body> <script> var x = ["Mohan", "Kriti", "Salim"] x.push("Nikhil") document.write("[",x,"]") </script> </body> </html>
So, in the above code we have created a Array and initialised to the variable x.
var x = ["Mohan", "Kriti", "Salim"]
Below is how the values are positioned in the Array,
Then in the next line, we insert the element at the end of the Array.
x.push("Nikhil")
And we get the below output,
[Mohan,Kriti,Salim,Nikhil]
