Took the following quote directly for the clasp readme.md from its github repo:

V8 support take advantage of the performance boost of Chrome JavaScript engine:
Every ES2019 features (except ES modules)
Edit your appsscript.json manifest to choose between the Rhino and V8 engines
Typescript users should update their tsconfig.json with the "target": "2019" compiler option
