src: remove use of deprecated type v8::FastApiTypedArray
Browse files Browse the repository at this point in the history
In the examples where `v8::FastApiTypedArray` was used, there is
actually no advantage of using V8's fast API calls instead of regular
API calls. Therefore this CL just removes the fast API call targets
instead of adjusting them.
