npm/node-which

The `node-which` project is a Node.js module that replicates the functionality of the Unix `which` command, allowing users to find the first instance of an executable in the PATH environment variable. It is designed for developers working in Node.js environments who need to locate executables dynamically without caching results. The module supports both asynchronous and synchronous usage, with options to override PATH and PATHEXT variables, making it versatile for various use cases.
