Finding the count of numbers divisible by a number within a range using JavaScript

Problem

We are required to write a JavaScript function that takes in a range of two integers as the first argument and a number as the second argument.

Our function should find all the numbers divisible by the input number in the specified range and return their count.

Example

Following is the code −

const range = [6, 57]; const num = 3; const findDivisibleCount = (num = 1, [l, h]) => {    let count = 0;    for(let i = l; i <= h; i++){       if(i % num === 0){          count++;       };    };    return count; }; console.log(findDivisibleCount(num, range));

Output
