Lab2 - My First Pull Request

This is my first pull request: base64-js

I changed a little spelling mistake in its package.json, and I also put more keywords in there.

I feel really good about what I did. This is the first time I work with other people's project on github.

Will he accept the changes? I don't know. Hopefully he will.

No matter he will accept my pull or not, I am going to keep working on Open Source from now on.
