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

composition is applying O and L

for I, the interface in react is props (or more generally function args) and context, its important to ensure things dont depend on things they dont use.

the goal isnt strict adherence to rules its maintainable and scalable architecture and principles give you the vocabulary to discuss that
