How to push to an array in a particular position?

rated 0 times [ 112] [ 5] / answers: 1 / hits: 60434 / 13 Years ago, fri, january 6, 2012, 12:00:00

I'm trying to efficiently write a statement that pushes to position 1 of an array, and pushes whatever is in that position, or after it back a spot.

array = [4,5,9,6,2,5]



#push 0 to position 1



array = [4,0,5,9,6,2,5]



#push 123 to position 1



array = [4,123,0,5,9,6,2,5]

What is the best way to write this? (javascript or coffeescript acceptable)

Thanks!
