how to switch branches in git

git switch <branch_name>

git checkout <branch_name> 

[git checkout "branch_name"]

is another way to say:

[git checkout -b branch_name origin/branch_name]

in case "branch_name" exists only remotely.

[git checkout -b branch_name origin/branch_name] is useful in case you have multiple remotes.

Regarding [git checkout origin 'another_branch'] I'm not sure this is possible, AFAK you can do this using "fetch" command -- [git fetch origin 'another_branch']

$ git checkout <existing_branch>

$ git checkout -b <new_branch>

git switch branch_name

git checkout branch_name 

$ git checkout -b myfeature dev

git checkout [branch name]

$ git checkout feature

wonder.woman@highfive project %  git checkout branch_name 
#this let you keep edited files
wonder.woman@highfive project %  git switch branch_name  

$ git branch iss53
$ git checkout iss53

Github branch 
pull request in branch

$ git branch
