  • The function takes two Array arguments,this: left andright, and returns an Array.

  • Examples are provided in both JavaScript and Python demonstrating the use ofArray.pow with various inputs.

 On an element-wise basis, raises the first value to the power of the second.

UsageReturns
Array.pow(right)Array
ArgumentTypeDetails
this:leftArrayThe left-hand value.
rightArrayThe right-hand value.
