@babel/plugin-transform-sticky-regex

What is @babel/plugin-transform-sticky-regex?

The @babel/plugin-transform-sticky-regex package is a plugin for Babel, a JavaScript compiler, that transforms sticky regexes (regular expressions with the 'y' flag) into an equivalent form that can be executed in environments that do not support the 'y' flag. This ensures compatibility across different JavaScript environments, including older browsers or JavaScript engines.

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

Transformation of sticky regexes

This feature allows the transformation of sticky regexes, which use the 'y' flag, into a form that can be executed in environments that do not support this flag. The code sample demonstrates how a sticky regex is transformed by the plugin.

"use strict";\n\nvar _regexp = /o+/y;\n\nvar _regexp2 = babelHelpers.wrapRegExp(/o+/, {\n  sticky: true\n});

It covers a broader range of regex features, including but not limited to sticky regexes, making it a more comprehensive solution for regex compatibility issues.
