rollup-plugin-ternary-replacement v0.0.2

---

Brief annotation

"rollup-plugin-ternary-replacement" is a plugin for popular web-applications builder called "rollup". This plugin can help developers to make their web-applications more compatible by replacing some of new ECMAScript features such as "??" operator by ternary operators. Replacing will be done automatically if plugin function call have been placed into rollup plugins configuration. Plugin convertion is performed without violating program logic and program flow disruptions. Different optional parameters allow to configurate plugin for developer's own needs. For example, developer can choose specific group of features that should be rapleced, or exclude certain files from conversion process. Plugin works correctly with both vanilla ECMAScript and framework syntax (also included jsx/tsx syntax).
