The difference between Babel parser and acorn


knowacornIs the parser of JS, I also knowbabel-parserIt’s also a JS parser, but what’s the difference between them?
first,@babel/parser(previously Babylon) fromacornFork comes out, but it’s basically rewritten, but someacornThe algorithm is still popular.

There are still some differences between them:

  • @Babel / parser does not support third-party plug-ins.
  • Acorn only supports the proposal of the fourth stage (basically equivalent to writing the standard, but it’s just a matter of time. See here).
  • The ast format is different, but you can start the estree plug-in of @ Babel / parser to match the ast format of acorn
