Webbinary-searching. Binary search on arrays for predecessor, successor and range queries. Rationale. The main reason for using a binary search or ordered set data structure instead of a hash map is to support fast predecessor/successor queries. Besides this library, I am aware of no other modules on npm which implement these semantics (making them … WebWith 100 elements, the linear search performs on average 50 comparisons, while the binary search performs only 6 or 7, so it is doing about 10X more "work" in the same amount of time. If you really like optimization, you should read two posts that use vector and conditional move instructions to optimize both the linear and binary search.
