# Usage of return in loops in JavaScript

The fact that `return` is located inside the loop may not always be a mistake. In the following example, a function is made that determines how many first elements of an array must be added so that the sum becomes greater than or equal to `10`:

`function func(arr) { let sum = 0; for (let i = 0; i < arr.length; i++) { sum += arr[i]; // If the sum is greater than or equal to 10: if (sum >= 10) { return i + 1; // exits the loop and the function } } } let res = func([1, 2, 3, 4, 5]); console.log(res);`

And in the following example, a function is made that calculates how many integers, starting from `1`, must be added so that the result is greater than `100`:

`function func() { let sum = 0; let i = 1; while (true) { // an infinite loop sum += i; if (sum >= 100) { return i; // the loop runs until it exits here } i++; } } console.log( func() );`

Write a function that takes a number as a parameter and divides it by `2` as many times until the result is less than `10`. Let the function return the number of iterations it took to achieve the result.
