Why the promise-like interface? If it returned a promise with a this-returning progress method monkey-patched onto it, then you could use it otherwise like a regular promise:


I guess I just still have bad memories of jQuery's old almost-like-real promises. I'd rather never have to think ever again about whether I'm dealing with a real promise or one that's going to surprise me and break at run-time because I tried to use it like a real one.

If you want to use a real Promise, you can wrap the call to recognize in Promise.resolve:

  Promise.resolve(Tesseract.recognize(myImage)).then(result => console.log(result))
