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.

What are @babel/plugin-transform-unicode-regex's main functionalities?

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;
