## What it is
JSVerbalExpressions is a JavaScript library that provides a fluent, chainable API for constructing regular expressions without writing raw regex syntax. It wraps JavaScript's RegExp object with readable methods like startOfLine(), then(), maybe(), and anythingBut().

## Use cases
- build regex patterns without memorizing regex syntax
- validate URLs with readable code
- construct complex match patterns programmatically
- replace cryptic regex strings with chainable method calls
- test whether strings match a pattern built step by step

## When to choose
- you find raw regular expressions hard to read or maintain
- you want to build regexes dynamically in JavaScript or Node.js
- your team prefers fluent, self-documenting pattern construction

## When to avoid
- you need maximum regex performance for hot paths
- you need advanced regex features not exposed by the fluent API
- you are working outside JavaScript/Node.js

## Facets
- artifact type: library
- maturity: stable
- function: parser, developer-tools
- domain: developer-tools, programming-languages, web-development
- platform: browser
- tags: regex, regular-expressions, fluent-api, builder-pattern, javascript, nodejs
