About this app

Binary Search is an interactive coding-basics lesson that compares three ways to find an item: scanning one position at a time, repeatedly halving a sorted list, and using labels to jump directly to a position. Learners complete guided challenges, count how many looks each method takes, and see why ordering or labels can greatly reduce search effort.

Use cases

  • Beginners learning search algorithms
  • Teachers demonstrating linear and binary search
  • Students comparing search efficiency
  • JavaScript learners practicing algorithm concepts

Features

  • Three interactive search-method tabs
  • Step-by-step Next and Reset controls
  • Challenges for finding present and absent items
  • Sorted-list binary search with a visible lookup trace
  • Look-count comparisons for different list sizes
  • Optional sound toggle
