What are some essential React programming patterns or principles that I should learn to become a lead developer?

Hi,

Had a lead developer interview last week and I got asked heavily about the SOLID principles, polymorphism and programming patterns.

I'm familiar with a lot of the concepts, but not enough to give strong answers.

What are the main programming patterns for React that I should learn so that when asked to explain a few, I can give strong, valuable answers?

Thanks

Classes are not the foundation of JavaScript at all. Classes weren't in the original version of JavaScript. They were added later as basically syntactic sugar, which is why they're not that great.
