## What it is
Trine is a functional programming utility library for modern JavaScript, in the vein of lodash, underscore, and Ramda. It structures utilities to work with the proposed function bind operator (::), placing data as the `this` parameter to enable fluent, pipeline-style composition over arrays and ES6 iterators.

## Use cases
- write functional-style data transformation pipelines in JavaScript
- compose array and iterator transformations fluently
- use utility functions with the ES bind operator
- replace lodash with a functional-first utility library
- work with ES6 iterators and generators functionally

## When to choose
- you use the function bind syntax proposal and want utilities designed for it
- you prefer data-last/this-based functional composition over lodash's argument style
- you work heavily with ES6 iterators and generators

## When to avoid
- you need a maintained library with active support
- you don't use the bind operator, since the API is awkward without it
- you need a battle-tested production utility library like lodash or Ramda
