## What it is
A jQuery plugin for validating form fields in the browser with visually appealing error prompts. It supports built-in validators (email, phone, URL, dates), custom and AJAX-based validation rules, and bundled locale translations.

## Use cases
- validate html form fields client-side
- show inline error messages on form inputs
- validate email phone and url inputs in the browser
- add ajax-based custom validation rules to forms
- localize form validation error messages
- validate forms in legacy browsers like IE6-8

## When to choose
- you maintain a legacy jQuery codebase needing form validation
- you need multilingual validation error prompts out of the box
- you want class-attribute-based declarative validation rules
- you must support very old browsers

## When to avoid
- you are starting a modern project without jQuery
- you use a modern framework with its own form validation (React, Vue, Angular)
- you need actively maintained software with regular updates
- you need TypeScript support or modern build tooling
