prefer-exponentiation-operator

Math.pow(base, exponent) and base ** exponent compute the same number. The operator is shorter, reads like the arithmetic around it, and also works with BigInt, where Math.pow throws.

--fix rewrites the call and adds parentheses where the result needs them.

Examples

Reported:

const area = Math.PI * Math.pow(radius, 2);
const distance = Math.sqrt(Math.pow(dx, 2) + Math.pow(dy, 2));

Not reported:

const area = Math.PI * radius ** 2;
const distance = Math.sqrt(dx ** 2 + dy ** 2);
