Sep 1, 2025Month: 2025-09. Delivered a core library enhancement in dfinity/new-motoko-base: Binary Search utility for Array, VarArray, and List. Implemented binarySearch() to efficiently locate elements in sorted collections, returning index or insertion point. Added comprehensive tests for empty and boundary cases, single-element, and duplicates. Commit 496a1e40ca8bc602aedf1cebe10aaf366b61596d; PR #375. This feature improves lookup performance, reduces linear scans in user code, and strengthens the core collection APIs.
