The Increment operator (++) increments its operand by one.
The increment and decrement operators are commonly used in for loops, for example:
Math.pow() or **
Exponentiation makes the second operand the power of the first operand (ab).
Use Math.pow to find the nth root of a number.
Finding the nth roots is the inverse of raising to the nth power. For example 2 to the power of 5 is 32. The 5th root of 32 is 2.
