Quoting the blog post:
“[Babel 7.23.0] includes transform support for the Decorator Metadata, Source Phase Import, Deferred Import Evaluation, and Optional Chaining Assignment proposals. We also updated our parser to support the new TypeScript 5.2 version, and added a transform option to let you use the .ts
extension within TypeScript imports.”
“In addition to releasing version 7.23.0, we also recently published the first Babel 8 alpha release!”
