From Git version 2.28 onwards, you can set a different name for the initial branch. To To set main as the default branch name do: $ git config --global init.defaultBranch main Checking Your Settings If you want to check your configuration settings, you can use the git config --list command

When you are downloading directly from this master branch. Do not make pull requests to this branch. 122  develop - This is the working development branch. All proposed code changes and contributions contributions by the community are pulled into this branch. When you make a pull request to the Laravel project, this is the branch you want to pull-request into. Once certain milestones have been reached and/or

restricted: The new value must not lead to a change of the active object branch. Also, when the �elds of a particular branch are speci�ed during object construction, the corresponding discriminator value changing the active object branch, replace the old object in memory with a new one completely: Starting with version 0.20 system.reset cannot be used anymore to support object branch changes as this never possible values of the discriminator variable in a case statement branch are a subset of discriminator values for the selected object branch, the initialization is considered valid. This analysis only works

// do something 5| } if and else are keywords. Like many other programming languages, the else branch is optional. The InitSimpleStatement portion is also optional. It must be a simple statement (§11) if-else control flow forms one implicit code block, one if branch explicit code block and one optional else branch code block. The two branch code blocks are both nested in the implicit code block. Upon Upon execution, if Condition expression results in true, then the if branch block will get executed, otherwise, the else branch block will get executed.
