ustring

ustring is a lightweight string utility library providing common string operations such as toLowerFirst, toUpperFirst, hyphenate, humanize, camelize, endsWith, and validation helpers like is.alphanum and is.match. Current stable version is 1.4.1, with no active development (last release in 2017). It uses a simple CommonJS export pattern and has no dependencies. Alternative libraries include lodash and ramda, but ustring is smaller and more focused on string manipulation.
