Fixes #13

@therohitramesh By the style guide I meant something like https://github.com/fossasia/open-event-frontend/blob/development/docs/style-guide.md

So it's just a text file? So it doesn't need to be mentioned in package.json also?

[lunaticmonk]

@therohitramesh Correct. It;s just a style guide.

@therohitramesh Since everyone writes different code. By different code, I mean the indentation, quotes, etc. We need to ensure that the code looks good and the coverage is also good. That's why. Also I will write tests in upcoming days for the same.
