How are you using Babel?

Programmatic API (babel.transform, babel.parse)

Input code

Another error I ran into while fixing #14123, and the fix for that will include a fix for this too. Compare the following runs of the parser, one with errorRecovery set to false, the other to true:

require("@babel/parser").parse("0b111199", { errorRecovery: true }).errors

require("@babel/parser").parse("0b111199", { errorRecovery: false })

See it here: https://runkit.com/tolmasky/incorrect-missingsemicolon-syntaxerror-when-errorrecover-set-to-false

You'll see the first gives you the error you expect: Expected number in radix 2. (1:6), while the second gives you an erroneous error of Missing semicolon. (1:6).
