## 🏁 Goal
|
|
|
|
This package provides utility functions and classes for make ESLint custom rules.
|
|
|
|
For examples:
|
|
|
|
- [getStaticValue](https://eslint-utils.mysticatea.dev/api/ast-utils.html#getstaticvalue) evaluates static value on AST.
|
|
- [PatternMatcher](https://eslint-utils.mysticatea.dev/api/ast-utils.html#patternmatcher-class) finds a regular expression pattern as handling escape sequences.
|
|
- [ReferenceTracker](https://eslint-utils.mysticatea.dev/api/scope-utils.html#referencetracker-class) checks the members of modules/globals as handling assignments and destructuring.
