Useful scripts

Its recommended to use prettier and eslint plugin in your text editor/IDE, so it can auto fix code. See the recommended VS Code extensions below. If you don't want to you can always use the following commands that will do the same:

   $> npm run format
   $> npm run format:check
   $> npm run lint
   $> npm run lint:check

format = Will format the code with prettier.

format:check = Will check the code with prettier.

lint = Will eslint the code for you.

lint:check = Will check the code with eslint.

We are using husky to check if the code passes lint and prettier standards.
