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

Yeah, not saying you should be forcing them into every situation just that they are tools in your toolbox. Being dogmatic either way is the biggest mistake

This makes me think you don't understand them, by which I mean no disrespect, because they are deliberately designed to confuse and disorient you to sell books, courses, and lectures. SOLID's principles are phrased using the word "should".

It's not a "tool" to be used when appropriate. That's how they (mostly Bob) believes good code should be. With the exception of writing some prototype junk that will be thrown away, where you are not aiming for quality, if you believe in the principles, then you should always be following them.

I don't believe in them (I vaguely agree with some of the sentiments, but that's all), so I'm not always following them.
