## What it is
A small Node.js library that wraps core modules like fs, child_process, crypto, dns, readline, and zlib so their callback-based APIs return promises. It lets developers use async/await with Node's standard library.

## Use cases
- promisify node.js fs methods
- use async/await with node core APIs
- wrap child_process exec to return promises
- convert callback-based node APIs to promises
- write cleaner async file operations in node

## When to choose
- you're on an older Node version without native promisified APIs and want promise-based core modules
- you want minimal wrappers around fs, crypto, dns, zlib, or child_process for async/await code

## When to avoid
- you're on modern Node.js, which provides util.promisify and native promise APIs
- you need actively maintained or feature-rich promise utilities
- performance is critical, since the wrappers add overhead

## Facets
