**execution-time** is a lightweight Node.js library that lets developers instrument their code with simple start/stop calls to measure how long a block of code takes to run, returning the elapsed time in milliseconds (and human‑readable strings). It supports multiple named timers and can automatically log results via any logging function (e.g., `debug`, `console.log`). The package is aimed at JavaScript/Node developers who need quick, zero‑dependency performance metrics while building or debugging applications.
