JavaScript Binary Search Typing Test

Practice typing a real JavaScript data structures and algorithms code snippet with this binary search implementation. Great for developers who want a code-based typing test instead of plain text.

Instructions

Type the JavaScript code exactly as shown, including indentation, spaces, brackets, parentheses, and semicolons. Focus on accuracy first before improving speed. This test is based on a real data structures and algorithms example, so every character matters.
