00:00 We're inside of a directory called utilityfunctions, which is a Git repo. Our project needs a new feature where we can take a string like "my favorite songs," and convert it into a string that's lower case with dashes in between, to be used in a URL.
00:16 To work on this new feature let's create and check out a new branch called URLSlugs. Now I'll run git-branch to make sure we are on our new branch as expected. Next, I'm going to create a new file in our directory called getURLSlug.js, and we'll open that file in our code editor.
00:35 Now, I'll work on this new feature, so I'm going to create a function called getURLSlug. I'm going to open the README file for the project in my code editor. I'm going to add to our documentation of examples with a new example for the function that we just wrote.
00:52 Now our new feature is complete, let's save and close this file. Back on our command line, let's run git-status. We can see that we do have our modified README as well as the new function. Our feature is ready to go.
01:06 Let's stage the new feature, and then we'll commit it to our current branch. Now that our feature has been built and it's stable, it's ready to be combined back into our main master branch. The way we do that is first, we need to check out the branch that we want to combine our current feature into.
01:25 Then we can run the git-merge command, and give it the name of the branch that we want to merge into our currently checked out branch. In this case that's the URLSlugs branch. When we run the git-merge command, Git automatically determines what type of algorithm to use to merge the two branches together.
01:44 In this case, our project history was linear enough that Git could use a fast-forward merge to combine the histories together. If Git can't do this, then it uses what's called a three-way merge, where it will create a new commit based on the merge.
01:57 Your code editor will pop up, and all you need to do is save and close the file, and a new commit will be created, and the merge will be finished. Now that our merge is complete, let's run git-status.
02:08 It looks like everything is good to go, and we can run git-push to push to our remote. If we want, we can delete this extra branch by running git-branch-d for delete, and the name of the branch, because it's been safely merged into our main master branch.
