Github allows you to store the source code of your application (on their servers).That is useful, because the hard drive of your own computer does not have eternal life.
In addition, it offers you the benefits of using Github, as you will learn to use a tool that is used very much in teams to work with all of the same piece of code.You can also choose whether to make your project private or public.
Projects that make your audience can be viewed by clients and can serve as advertisements for yourself.
The main goal of GitHub is to manage your git repositories.Git repositories are the collections of source code files of your projects.
You install git locally on your PC, change your commit to your Git repository, and then push your change to the GitHub server as well
All programmers within a team do this, and by regularly doing a pull on your local computer, the changes from the other programmers are also collected and merged into your local working directory.
Git can recognize very clever changes to different parts of a file and merge the changes from everyone.This way you prevent your version of a file from overwriting the changes that another one has just done to the same file. Everything is cleverly merged and everyone can edit the same files simultaneously.
You can easily get back to older versions from years ago, and you can see which programmers are responsible for what changes in the code.
With GitHub, you can also ask other programmers to review your code and give comments.This allows you to avoid problems before they end up in the production environment. If one or more programmers have found the code, you can merge (merge) your changes with the rest of the project and they can be continued to a staging or production environment.
Git offers many advantages to programmers, among others because you can create branches (branches) in your project and thus work on multiple tickets at the same time.Suppose you have to make three changes, you can create three branches based on the current develop branch. If any of the changes are finished, they can be offered to other programmers as merge-request. You often have to wait for it until other programmers have time to look at it. Meanwhile, in another branch, you can continue to work on another change without the previous change to the current branch code. Therefore, if that previous change is not yet up to production, other changes can be made to production effortlessly. Issue of the desired branches Mergen (merge) with the current develop or master branch.
Much of the above functionality is not so much GitHub functionality, but is functionality of Git itself.Github provides you with an environment to see and share the repositories online with others. Which programmers are allowed to make changes to which branches, changes must first be approved via a merge request and by how many people, before it enters the master branch.
Besides GitHub there are many other online tools that do about the same thing.So you have Atlassian bitbucket and Gitlab. I am very much a fan of Gitlab. This is why I use more than GitHub, but GitHub is the most famous of them all.
The main target is distributed versioning for software assets/projects.
Git repositories contain all the changes from the first time you check in the SRC Code of your project (push).When you have a backup of a git repo (clone) you have access to all versions of the SRC. Since every developer working on the project has the entire git repo on his computer, you can even browse the versions of your SRC code without the Internet.
Git is very efficient in determining textual differences in thousands of files and knows of each line, who, when it’s ticking.GIT also has an efficient branching model that allows a developer or a team to work isolated to a large feature, and then to make his big change with the latest development version: Without the work on the development version being stopped .
Github was one of the first major providers of Git repos on the internet.Open Source Projects-> free. As a result, a very eco system was created for developers who brought their open source projects under version control at Github.
(Pieces better and faster than SourceForge, which was the standard at that time).Add the extra tools, such as Issue tracker with the possibility to refer to changes in the SRC, Pull requests and code review and cheap expansion to private projects (7,-/month for infinitely many repos) and you understand the popularity.
