Зачем новичку учить Git

Git используется в большинстве компаний, где над проектом работает хотя бы два разработчика:

  • Новый человек приходит в компанию и клонирует репозиторий проекта на ПК.
  • Получает задачу, создаёт новую ветку и пишет код.
  • Когда всё готово — отправляет запрос на добавление кода в master-ветку.
  • Другие разработчики смотрят код, оставляют комментарии и указывают на ошибки.
  • Новичок дорабатывает код, обновляет master-ветку и переходит к следующей задаче.

Это общая схема того, как проходит командная работа в проекте. В ней не учтены правила использования Git, которые каждая команда пишет под себя. Например, у каждой команды свой порядок проверки кода и свои критерии его готовности для добавления в master-ветку.

Step 2. Create a Branch

Branching is the way to work on different versions of a repository at one time.

By default your repository has one branch named which is considered to be the definitive branch. We use branches to experiment and make edits before committing them to .

When you create a branch off the branch, you’re making a copy, or snapshot, of as it was at that point in time. If someone else made changes to the branch while you were working on your branch, you could pull in those updates.

This diagram shows:

  • The branch
  • A new branch called (because we’re doing ‘feature work’ on this branch)
  • The journey that takes before it’s merged into

Have you ever saved different versions of a file? Something like:

Branches accomplish similar goals in GitHub repositories.

Here at GitHub, our developers, writers, and designers use branches for keeping bug fixes and feature work separate from our (production) branch. When a change is ready, they merge their branch into .

To create a new branch

  1. Go to your new repository .
  2. Click the drop down at the top of the file list that says branch: main.
  3. Type a branch name, , into the new branch text box.
  4. Select the blue Create branch box or hit “Enter” on your keyboard.

Now you have two branches, and . They look exactly the same, but not for long! Next we’ll add our changes to the new branch.
