-// error = The error that was caught or `undefined` if nothing 
+// error = The error that was caught or `undefined` if nothing
 //   errored. If something other than an instance of `Error`
 //   was thrown, it will be wrapped in an `Error` object by calling
 //   `new Error()` on the thrown value.
