GIT - create a new remote branch from the local one
First, you must create your branch locally
git checkout -b your_branch
After that, you can work locally in your branch, when you are ready to share the branch, push it. The next command push the branch to the remote repository origin and tracks it
git push -u origin your_branch
Teammates can reach your branch, by doing:
git fetch
git checkout origin/your_branch

JAVASCRIPT vs ANGULARJS - copy object by value, not by reference
In JavaScript copy of object is done by reference:
var newObj = Object.create(oldObj); //Modification in newObj would be reflected in oldObj.
JavaScript solution 1: Inline deep copying (if you know its structure)
var newObj = {
name: source.name,
type: source.type
}
JavaScript solution 2: Use JSON parse (it could be more slower)
var newObject = JSON.parse(JSON.stringify(oldObject));
Angular way:
var newObject = angular.copy(oldObject);
var newObj = Object.create(oldObj); //Modification in newObj would be reflected in oldObj.
