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
18
