minor changes but lgtm otherwise

[jonathankao97]

minor but should we be mixing yarn and npm commands?

[joyliu-q]

Running yarn build runs npm under the hood.

[jonathankao97]

also minor but not sure how this command is being used, not seeing any tests or jest config

[joyliu-q]

Good catch, jest was added automatically when creating the project but deleted later. Thanks!
