ES2015 introduced several new Math methods that simplify common mathematical operations.
Using these modern methods improves code readability and intent.
This rule flags legacy patterns that can be replaced with:
Math.log10(): Calculates the base-10 logarithm
Math.log2(): Calculates the base-2 logarithm
Math.hypot(): Calculates the Euclidean distance (square root of sum of squares)

Math.hypot(...values: number[]): number
Returns the square root of the sum of squares of its arguments.
@param ― values Values to compute the square root for.
If no arguments are passed, the result is +0.
If there is only one argument, the result is the absolute value.
If any argument is +Infinity or -Infinity, the result is +Infinity.
If any argument is NaN, the result is NaN.
If all arguments are either +0 or −0, the result is +0.
