push information to an array but at index 0 [duplicate]

Question

I want to push information to an array I have created. The thing is I want to push the info to be first in the array, or at index 0. How do I do this?

I want to avoid having to reverse the array to get the most recent first as this makes things much complicated later..

e.g, my array may look like:

{"entry1":"entry1-value"}, {"entry2":"entry2-value"}

and I want to push a new value to be first:

{"newEntry":"newEntry-value"},{"entry1":"entry1-value"},{"entry2":"entry2-value"}

Have you tried anything?

Use unshift():

array1.unshift({'newEntry' : 'newEntry-value'});

JS Fiddle demo.
