mentioning strict mode

[amid11]

Function in if

let phrase = "Hello";

if (true) {
  let user = "John";

  function sayHi() {
    alert(`${phrase}, ${user}`);
  }
}

sayHi();

The result is an error.

The function sayHi is declared inside the if, so it only lives inside it. There is no sayHi outside.

When I execute the code I don't get any error unless in strict mode, I think it can be a good idea to remind others that in order to see the error we need to add `'use strict';' at the top of our code

Where to remind that? All code in the tutorial is use strict by default.

I meant for those who are running the code locally, in their own js files, It took me awhile to remember that I haven't used strict mode myself, so I thought a reminder wouldn't hurt anyone even though that was obviously my mistake.

I understand, but where to put the reminder?

Maybe here amid11@e198ff7

No, cause you see, there are many places in the tutorial like that. And also I believe strict mode is the past, not the present/future, don't like the idea of putting it into text at every such place.
