Don't use String::NewSymbol

String::NewSymbol is recommended by v8 docs for wrapping string data that represent commonly used keys. The reason is for lookups to be faster (https://bugs.webkit.org/show_bug.cgi?id=104082#c0). But in testing this is actually usually a deoptimization because creating new symbols is slower than strings. This is confirmed by this Node.js core commit Remove v8::String::NewSymbol() entirely: https://github.com/joyent/node/commit/f674b09f40d22915e15b6968aafc5d25ac8178a2.

can be done in node.js like nodejs/node-v0.x-archive#4201 (comment)
