Summing cubes of natural numbers within a range in JavaScript

Problem

We are required to write a JavaScript function that takes in a range array of two numbers. Our function should find the sum of all the cubes of the numbers that falls in the specified range.

Example

Following is the code −

 Live Demo

const range = [4, 11];
const sumCubes = ([l, h]) => {
   const findCube = num => num * num * num;
   let sum = 0;
   for(let i = l; i <= h; i++){
      sum += findCube(i);
   };
   return sum;
};
console.log(sumCubes(range));

Output
