Welcome to the Binary Search in Javascript page! Here, you’ll find the source code for this program as well as a description of how the program works.

```
const [, , array, target] = process.argv;
const error = 'Usage: please provide a list of sorted integers ("1, 4, 5, 11, 12") and the integer to find ("11")';
const binarySearch = (array, target, start = 0, end = array.length - 1) => {
const isOrdered = array.every((num, i, arr) => !i || num >= arr[i - 1]);
if (!isOrdered) return error;
const middleIndex = Math.floor((start + end) / 2);
const middleValue = array[middleIndex];
const newIndexes =
target < middleValue ? [start, middleIndex - 1] : [middleIndex + 1, end];
return middleValue === target
? true
: start >= end
? false
: binarySearch(array, target, ...newIndexes);
};
console.log(array && target ? binarySearch(array.split(', '), target) : error);
```
