Git is something that most of us use daily, though there are functions / commands you do not use but still may help in some situations.

Collection of JavaScript examples when it behaves...weird? Funny?

Have you ever heard about yarn resolutions? It is not something you would use everyday, but it is definitely useful.

The first thing you read about setState - it is asynchronous. I understand it but still did not realize a couple of things.

It was a great idea to use git and create portal like GitHub and share source code among other developers. One of the benefits is, you do not need to reinvent the wheel and just use package you need. And because lot of users will add it to their projects, it gets well tested. But I can see there a big problem: maintenance.

You commited something and right after that you saw you forgot to remove log or add another file? Or you just want to extend your message? It is not necessary to revert the commit everytime.

I am working on React app with couple of other developers. And you know it, you need this component, that functionality, etc. so you google it, install the package and the work is done. Is it ok to work like this? Do you even know what exactly you added to your project and do you really need it?

If you are working on a project, you sure use open source projects, libraries and frameworks. All these stuff helps you build something amazing and do it faster. And also you know what a good feeling it is, when someone write a good review or give your fan page like. So do the same.

You are creating an application that shows data to the user - doesn't matter if he is searching for some specific thing or he is only listing everything you have. What happens if the server responds with empty array? Or with error? Will your application show only empty space or an error message?

For a long time I didn't know that even writing commit message can have its own "best practices". When I got in touch with git for the first time, this part was described with words like "...and here you can write something short about what's going on in the commit".
