Hello to all development enthusiasts! Have you ever faced cumbersome business logic in your React or React Native components? Or have you ever wondered if there was a more efficient way to reuse certain business logic without reinventing the wheel? If so, this article will enlighten you on Custom Hooks.

Ah, tests! A word every developer has heard, but whose true value is often underestimated. In the bustling world of React and React Native development, tests play a vital role. But why exactly are they so important? And how to navigate the maze of E2E, unit, and functional tests? Let's explore this together.

Today, we're going to better define the different levels of seniority, to break stereotypes but also to better understand the different notions in which people place themselves.

Well, we no longer need to advertise this tool, which is an absolute must-have, but I realize in working with my clients that many do not know it or worse! They know it but do not use it (well, after all, everyone has their choices, we always have sometimes specific contexts, right). So let's go for an insight on this incredible tool!

In React Native, the concept of optimization is greatly undervalued. Generally, this topic is set aside for a long time before encountering a problem that quickly turns into an endless loop, a result of the negligence shown since the beginning of the project. There are many ways to optimize an application and listing them all would be too long! However, we can superficially look at some of these concepts, let's go!

Seniority is a concept everyone knows, and many reduce it to a 'number of years of experience'. Personally, I find this a bit regrettable because a senior is someone who will add value on many topics, and the number of years of experience is not a guarantee of being good in these different areas. Guidance and mentoring, implementation of processes, long-term technical choices, advanced debugging methodology, etc., etc... In short, today we debunk this notion where everyone puts their own definition into it!

Optimizations in React Native, part 2! We've already covered the optimizations in React Native to work on, and I've said that there are far too many topics to cover in one, or even two, articles, so we continue to dig a little by addressing other important concepts to pay attention to!

Optimization in React Native part 3 is here! We've already discussed this topic with several points for improvement, and we're now at the end of the series. Once again, there are still many things that could be mentioned, but it's already quite a lot 😌. Here, we're talking about libraries, Hermes, navigation, a bit of Redux, and memory consumption!

Git is an essential tool today for businesses. Let's not lie, it mainly concerns companies working in tech with code through applications and other software. But teams having documents and common work can also benefit from it. So, let's see together what Git is, why it's important, and how to use it!
