Here are _some_ of the most essential git operations you will need when working as a developer.
🧵🔽
1️⃣ Create A New Repository
This is the most basic command you'll need. When you start a repository locally, your start with git init.
2️⃣ Clone A Repository
You can clone a remote repository to get a local copy of it. Your local repository is connected to the remote one so you can pull in changes and push yours to the remote.
3️⃣ Stage Files For Commit
Staging files basically makes them available to be committed later. It's like telling git "Okay, the next time I want to save a bunch of stages, include this file and its changes".
4️⃣ Commit Your Changes
Committing your previously staged files creates a "version" of your repository. It includes all previous changes and the ones added with that specific commit.
You can, from then on, always rewind your repository to this exact state.
5️⃣ Add A Remote Repository
You can add as many remote repositories as you like to your local repository. Most people only work with one remote repository, but git is actually designed for more.
6️⃣ Fetch Remote Changes
Fetching pulls in the data from the specified remote repository. It doesn't merge the changes directly into your local branches and keeps them in a separate directory, named after the remote name.
7️⃣ Fetch And Merge Remote Changes At Once
Pull is a convenience command. It combines fetch and merge and saves you some writing and time.
8️⃣ Create A New Branch
Using checkout together with -b creates a new branch in your local repository. You can commit to it but you still have to push it later. Switch is an experimental alternative.
9️⃣ Push Your Local Branch
Push is what you need to get your changes to a remote repository. Others can then fetch, merge or pull them into their local versions of the repository.
🔟 Switching Branches
You can change the branch you currently work on with either checkout or the experimental switch.
1️⃣1️⃣ Stashing Changes
Sometimes you want to put your current unstaged changes aside and do something else. This is what stash is for. It's basically a stack where you can put changes atop and pop them off again later.
1️⃣2️⃣ Rename A Branch
Sometimes you'll want to rename a branch. There is, however, a difference in doing this locally and on the remote. This is why you'll need two commands for it.
1️⃣3️⃣ Apply A Commit From One Branch To Another One
Sometimes, you committed a change and want to apply it to another branch, as weell. This is what cherry-pick is for.
1️⃣4️⃣ Show Changes
The git log contains a list of all commits in descending order of application. The latest commit sits on top, the oldest commit is the last one on this list. You can use this to find out commit hashes and when someone applied what commit.

You hear some people talking about it, you might have a basic idea, but let's take a closer look because, in the end, it's not as difficult as it might seem from the outside!

1️⃣ What Is It?
Test-driven development (short: TDD) is a software development technique.
Instead of writing all your code first and only then writing your tests, you start with tests, then code a little, then test again, and so on.
It is one specific form of the test-first approach and aims at making software development faster, more reliable, and safer to do. And it especially forces developers into a user role.
By writing tests first, you become a user. You are the first one to ...
They are both deeply immutable, so you no longer need to Object .freeze() your objects or use libraries like Immutable .js to gain unchangeable objects, and do you know what's even more awesome?
You can compare them with the strict equality comparison (===), ...
WebAssembly has the chance to become for JavaScript what C, C++, and Fortran are for Python.
JavaScript has its limitations, as well as Python does. Python solves this by having an awesome native interface that allows easy integration ...
... of low-level libraries. JavaScript has C/C++ in Node. But in the browser? Sure, floating-point arithmetics can well be done with the help of WebGL and shader language, but there is no common low-level target for all of JavaScript.
Here are some resources that help you to get into the language!

1️⃣ "The Book"
This is the official Rust book. It covers everything the language has to offer and introduces feature after feature while enabling especially newbies to follow along from the simpler to the more difficult topics.
This project gives you small exercises that aim at getting you comfortable writing Rust code. Especially if you don't feel creative enough to think of a new project, this is a great way of still writing code.
The most-loved language, according to StackOverflow's yearly developer survey that not enough people seem to use professionally.

1️⃣ What Is Rust?
Rust is a systems programming language that is compiled to binary. It has no runtime and instead uses a concept called "borrow checking". Developers don't need to explicitly free memory, the compiler does it for them.
The language itself is multi-paradigm, offering functional, generic, imperative, structured, and concurrent programming with a huge emphasis on performance, memory safety, and developer productivity.
