Push data into a certain position in an array

Question

How do I push some data into a certain place in an array?

I am trying the code below:

Keys[1].push({ Keys: "Test" });

But it doesn't seem to work as expected

The method you are looking for is splice

arrayObject.splice(index,0,{Keys:"Test"});
