The best way is the most natural : speaking it, regardless of ability.

Get a native speaker, ask them to teach you the very basics, get them to keep speaking the language to you and correct you as you go. It doesn't matter how laborious it is as long as you're _active_.

At the point you can get a basic conversation going you can start actually looking at the grammar and the written language.

As a human being, your brain is made for spoken language first. Writing is still new and cognitively less important.

I speak 4 languages, each learned in a completely different way.

We can argue what "best" means, but from my experience the fastest is buy a grammar with exercises, read the grammar and do the exercises.

It's extremely hard work for the other person until you're past a certain level. I tried this, and they struggled even though I could already speak a bit, they they were a professional and I was paying them well. If you're at zero, this is fantasy.
