#composition vs inheritance

If you're a senior developer or architect, I bet you know the most popular concepts, design patterns, and how stuff works inside. But still, not many front-end devs go think so much about composition and inheritance. It's not an often discussed topic, and I've noticed not all devs can explain why they created their solution with this or this way. In today's article, we'll talk about two programming concepts, composition and inheritance. I will tell you what composition is and what inheritance is, but not only. You'll learn about how they look in js as well in react.js. Next, we'll compare them together and look at which one is better to use, when to use composition and when it is better to go with inheritance. Because it's an article related to composition vs inheritance targeted to React, I will not go very deep in programming concepts as inheritance or composition in general. I will just explain them shortly, and I'll focus on the topic - the comparison.

I needed to read this this morning. Having been challenged on a design principle by my incredibly astute co-worker, I went out on a google hunt for pros/cons on the model he suggested ... and after reading through a multitude of pages, still not arriving at a clear understanding why I should change to this proposed model, found this. It's not a particularly mind blowing article, but the message is important.  Everyone has a notion as to how something should be done.  More educated / experienced people have very strong notions as to how something should be done.  Everyone has done work in the past they wish they could re-do because they are embarrassed with the naive / bad choices they made - no matter how they thought that project should be executed.  Most of us have actually met goals / deadlines with this now-seen-as shoddy / naive work.  And in three years, the work we are doing now will be seen as shoddy / naive and frightening that it was released / used / made public / etc. Deadlines keep us pragmatic.  Without pragmatism, we would have a beautiful, highly-detailed sketch on onionskin.  With realistic constraints, we may have a blocky, somewhat taped-together object- but something that actually does a thing and produces a result. I need to get a bit more assertive with this observation at times ...
