When adding eslint into your project you ensure that everyone uses the same settings. If you change your VsCode-settings and I want to collaborate to your repo - how do I get your lint-settings? ;)

Okay for unit tests it's pretty simple. You write code that tests your code. Imagine you have a function that adds two values

function add(first, second) {
  return first + second;
}

To test your function with ava you could then say something like

/*
  you define what the result of your function SHOULD be.
  If your implementation of the add function was broken, 
  this would return an error telling you exactly what is wrong.
  */
test("add function returns 3", t => {
  t.is(add(1, 2), 3); // <-- this passes because 1+2 does indeed equal 3.
  // The line can be read as "Please ensure that the result of add(1, 2) equals 3"
});

I hope it makes sense!

Cypress is purely for UI to help you simulate user inputs. You could write cypress-tests that click a textbox, enter a specific text and hit your sign-in button. All automated.

Thanks a lot for explaining the concepts!
I'll definitely try to implement them.
