How to use math operations for starting to ending values

  **Your code so far**


function sumAll(arr) {
let start=Math.min(arr[0],arr[1])
let end =Math.max(arr[0],arr[1])
let total=0;
for( let i=start; i<=end; i++){
  total+=i;
}
return total;
}

console.log(sumAll([1, 4]));

Do you mean the Math module, being used here?

let start=Math.min(arr[0],arr[1])

It is a JS object with various properties and methods. When in doubt, read the documentation.

Right, it a function to take all the numbers in a range, and sum them, or add them together.

If your range is 2 to 5, then you would add together the numbers 2, 3, 4, and 5. The answer would be 14.
