Thank you for the article, it is very useful. Although, I would suggest adding at least one example in actual React code to show the use cases :) Cheers

Thanks for the feedback @Alp3n. I will add an actual React snippet at the end that uses some of these concepts.

[Bhanu Teja Pachipulusu](https://hashnode.com/@pbteja1998) Thank you. I started my first real React project few days ago and already used most of these. What I learn here is optional chaining and I think I have a place for that in my app :D Also default parameters, I have read about them before, but now I might use them too :)
