## What it is
js-cookie is a simple, lightweight JavaScript library for reading, writing, and deleting browser cookies on the client side. It is RFC 6265 compliant, dependency-free, under 800 bytes gzipped, and ships both ES module and UMD variants.

## Use cases
- set and get browser cookies in javascript
- create cookies with expiration dates
- read all cookies visible to the current page
- custom cookie encoding and decoding
- manage cookies across a website in the browser

## When to choose
- you need a tiny, dependency-free cookie utility for the browser
- you want broad browser support with ES and CommonJS/AMD module compatibility
- you need RFC 6265 compliant cookie handling with custom converters

## When to avoid
- you need server-side cookie handling in Node.js rather than the browser
- you want a full state-management or storage solution like localStorage wrappers
- you need cookies with HttpOnly or Secure flags set from the client, which browsers do not allow
