A small Node.js utility that checks whether a given CLI argument list (defaults to process.argv) contains a specific flag, returning true or false. It supports checking short and long flags and stops searching after an -- argument terminator.

Recent updates
v5.0.1
Release v5.0.1 makes a small change related to how `process` is accessed. It updates the package version and modifies the implementation to explicitly import the `process` module for use as the default source of `process.argv`.
v5.0.0
v5.0.0 is a major release of has-flag that raises the minimum Node.js version to Node 12 and switches the package to pure ESM. The code changes are small, but they include packaging and TypeScript surface-area adjustments that can affect consumers relying on CommonJS or deep imports.
Breakingv4.0.0
v4.0.0 introduces TypeScript type definitions and updates the supported runtime requirements. The primary upgrade concern is that the package now requires Node.js 8, which may break older Node versions.
