Process Running Status

The `is-running` package provides a minimalist and direct utility for Node.js environments to ascertain if a process with a specific Process ID (PID) is currently active on the system. As of its latest stable release, `2.1.0`, the library focuses on a single, clear function: returning a boolean indicating the presence of a process for a given PID. The package maintains a stable, albeit infrequent, release cadence, with its core functionality having remained consistent since its last major update. Its primary differentiator lies in its extreme simplicity and lack of external dependencies for runtime, making it a lightweight choice for basic process monitoring or cleanup tasks, especially when compared to more comprehensive process management libraries that offer broader control and information beyond just status checks.
