How can you create a new branch in the Git version control system and what methods are available for this?

In Git, creating a new branch can be done in several ways:

• Using git branch:

git branch branch_name

This command creates a branch but does not switch to it.

• Using git checkout with -b:

git checkout -b branch_name

Creates a new branch and switches to it immediately.

• Using git switch (more modern method):

git switch -c branch_name

Similarly, it creates and switches to the new branch.

All these methods create a branch based on the current commit (HEAD). To create from another commit, specify it explicitly:

git branch branch_name commit_hash

or

git checkout -b branch_name commit_hash

The choice of method depends on preferences and Git version.
