Add lint for this project

I don't sure that I can't know your code style.
(Maybe you use 4 space and 2 space in this project)

So can you use linter for this project(example: eslint)?

Yeah great idea, I missed this out. I will get something in 👍

I create a PR that can resolve the lint problem

Sorry it's taken so long, if any1 is interested I added prettier into the project.
