## What it is
A small JavaScript library that lets you make JSONP requests using the same promise-based API as the native Fetch API. It provides a global fetchJsonp function with configurable callback names and timeouts.

## Use cases
- make JSONP requests with a fetch-like API
- fetch cross-domain JSON from legacy APIs that only support JSONP
- customize the JSONP callback parameter and function name
- set timeouts on JSONP requests
- parse JSONP responses as promises

## When to choose
- you need to consume a legacy third-party API that only supports JSONP
- you want a fetch-style promise API for JSONP in the browser
- you need configurable callback names and request timeouts for JSONP

## When to avoid
- the API supports CORS and you can use standard fetch
- you need POST or other HTTP methods since JSONP is GET-only
- you are building a server-side application where JSONP is irrelevant
- you are concerned about JSONP security implications in modern apps
