Initializing an Array with a Single Value

Question

Is there a more compact way to do this sort of initialization?

for (var i = 0; i < arraySize; i++) array[i] = value;

Answer 1

For efficiency, I would avoid push. So simply

for (var i = 0; i < arraySize; i++) array[i] = value; 

For IE10:

array = new Array(arraySize); 
for (var i = 0; i < arraySize; i++) array[i] = value; 

Edit: modified as discussed in the comments.
