@babel/plugin-transform-unicode-regex
Advanced tools
The @babel/plugin-transform-unicode-regex package is a plugin for Babel, a JavaScript compiler, that transforms Unicode regular expressions into equivalent ES5 syntax. This is particularly useful for ensuring compatibility with older environments that do not support Unicode property escapes in regular expressions.
Transform Unicode Regular Expressions
This plugin transforms Unicode regular expressions like the one above into an ES5-compatible syntax. The 'u' flag in the regular expression indicates that it's using Unicode mode, which is not supported in older JavaScript environments. The plugin will convert this to a form that can be understood by these environments.
const regex = /\p{Script=Greek}/u;regexpu-core is a package that also compiles Unicode regular expressions to ES5. It is similar to @babel/plugin-transform-unicode-regex but can be used independently of Babel. It provides a low-level API for transforming regular expressions and is used by Babel itself.
This is a legacy Babel plugin that was used to transform Unicode regular expressions in ES2015 (ES6) code to be ES5-compatible. It has similar functionality to @babel/plugin-transform-unicode-regex but is specific to the ES2015 preset. It is now deprecated in favor of the unified @babel/preset-env.
