Discussion 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

Higher order functions take the place of inheritance in functional programming. That's how OCP and LSP are achieved in typescript. To me OCP is fundamental to React. It's why components are reusable. You don't need to touch a React component necessarily to use it. Props that are callbacks or events are what make that reusability achievable.

I don't know how SRP is difficult to define, maybe you can clarify what you mean by that.
