This Babel plugin, @babel/plugin-bugfix-v8-static-class-fields-redefine-readonly, addresses a specific bug in older V8 versions related to redefining static class fields marked as readonly. Without this fix, attempts to redefine such fields can silently fail or lead to unexpected behavior. This plugin ensures correct behavior by transforming the code to work around the V8 issue. It's especially useful for libraries and applications targeting environments with older V8 engine versions.
