Node.js 0.12 path.isAbsolute() ponyfill

Last verified Sep 9, 2026 against path-is-absolute@2.0.0.

path-is-absolute ships CommonJS only. require("path-is-absolute") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.10.0. import "path-is-absolute" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

**Deprecated:** This package is no longer relevant as Node.js 0.12 is unmaintained.
