Create a basic CI file

[poush]

In this task, a basic Travis CI file needs to be created. The name of the file will be .travis.yml and for now, we need basic checks only. It should run tsc command.

You can try to improve with more checks but for now tsc is required.

Just to clarify you wanted a tsc command on the existing YAML file right?

I forgot that the old Travis file was still there in the codebase. Can you also remove npm run test
and instead, put npm run lint and tsc in respective order.

Do we need to add the Travis badge, if so, can I get the link?
