babel-plugin-transform-es2015-unicode-regex compiles ES2015 Unicode regular expressions to ES5 compatible code. It transforms Unicode regex flags (like u) into equivalent, albeit potentially less performant, ES5 alternatives. This plugin ensures that regular expressions leveraging Unicode character properties work flawlessly in older JavaScript environments lacking native support. Use this to maintain compatibility without sacrificing modern regex features in your codebase. Enable it for broader browser support when utilizing Unicode regular expressions.
