    Handle onError callback with optional argument (#43436) · 7cf362fc
    Nate Bosch authored
    Check for a binary callback first since a function with an optional
    second argument will match both typedefs.
    
    Remove documentation around a synchronous error following some other
    error or value - a synchronous error can never follow a value or an
    asynchronous error. If there is a synchronous error it will _always_ be
    the first thing to happen.
    
    Add a test for a unary error handler and an error handler with an
    optional stack trace argument.
