Ask HN - what is the best method to learn how to code?

I'm a business guy but I want to learn how to code as a frontend developer.

Which method is more effective?

1. Should I learn by doing? I have a website and want to improve it. Will I be able to teach myself by trying to fix features?

or

2. I pick up books and start from scratch? And only then, after reading the material I will be ready to make something happen?

Please advise. Thanks!
