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

I think this is nice, short and elegant:

// assuming `value` is what you want to fill the array with
// and `arraySize` is the size of the array
Array(arraySize).fill(value);
