[JavaScript] - Using JavaScript: Writing an O(log n) Algorithm

Learn how to implement a Binary Search algorithm to quickly and efficiently retrieve an integer from a sorted array of distinct values.

👩‍💻 Technical question

Given a sorted array of distinct integers and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. Is it possible to write an algorithm with O(log n) runtime complexity? Examples: Input: values = [1,3,5,6], target = 7. Output: 4 Input: values = [1], target = 0. Output: 0
