Implementing Math function and return m^n in JavaScript

We are required to write a JavaScript function that takes in two numbers say m and n. Then function should calculate and return m^n.

For example − For m = 4, n = 3, then

power(4, 3) = 4^3 = 4 * 4 * 4 = 64
power(6, 3) = 216

The code for this will be the following using the power() function in JavaScript −

Example

const power = (m, n) => {
   if(n < 0 && m !== 0){
      return power(1/m, n*-1);
   };
   if(n === 0){
      return 1;
   }
   if(n === 1){
      return m;
   };
   if (n % 2 === 0){
      const res = power(m, n / 2);
      return res * res;
   }else{
      return power(m, n - 1) * m;
   };
};
console.log(power(4, 3));
console.log(power(6, 3));

Output

And the output in the console will be −

64
216
