JavaScript | Math.pow( ) Function

The Math.pow() function in JavaScript is used to power of a number i.e., the value of number raised to some exponent. Since, the Math.pow() is a static method of Math and therefore it is always used as Math.pow() and not as a method of an object created of Math class.

Math.pow(base, exponent)

Parameters:

  • base: It is the base number which is to be raised.
  • exponent: It is the value used to raise the base.

Return Value: The Math.pow() function returns a number representing the given base raised to the power of the given exponent.
