dsh-is-square

Checking whether an integer is a perfect square may seem trivial, but it shows up constantly across model-inference pipelines, educational tools, and math validation workflows. Most solutions pull in external math libraries or fire off a network request, adding unnecessary complexity to what is fundamentally a single arithmetic operation.\n\ndsh-is-square keeps things radically simple: a pure Node.js implementation with zero network dependencies and zero third-party runtimes. It does one thing and only one thing. It tells you whether a given number is a perfect square. No side effects, no external services, fully offline-capable, and easy to slot into a reasoning workflow as a lightweight utility node.\n\nIt is well suited for developers who need a quick math check inside an inference pipeline and want to keep their dependency footprint as small as possible, especially in offline or resource-constrained environments.
