Our mission: to help people learn to code for free. Taking that to the next level, some linters will actually allow you to pass in an argument to the command running the linter that allows it to fix it for you automagically. Now that we can format our code automatically, we should be able to fix our code automatically! By default, tslint outputs to stdout, which is usually the console where you're running it from.
