As a git noobie I am beginning get get my head around git's version
control philosophy. I am now trying to understand the purposes of
branches or rather when to use them. In my case I have a Java
application under version control with git. I am planning to port it
into a mobile app. Is that an appropriate use of branches or should it
be created as a new repository? What is the relationship between the
same source code in different branches? Do changes to code in one branch
get ported to another branch somehow or do all changes then have to be
made twice? The documentation tells how to branch but not the general
philosophy behind it from a best practices standpoint. Thanks in advance
for any insight.
