KMP String Matching Algorithm: Theory, Implementation, and Comparison with Other Search Methods
This article explains the KMP string‑matching algorithm, how it builds the prefix (next) table to avoid the O(M·N) worst‑case of naive search, provides JavaScript implementations, compares it with Boyer‑Moore and V8's indexOf strategy, and includes detailed code examples.
