Multiple i"if" values?

Question

I have made my first js script and I was wondering, is it possible to add multiple values to a "if var =="

var day = window.prompt("How was your day? Describe it in 1 word!");

if (day == null, "bad", "terrible") {
    document.write("How come?");
} else {
    document.write("sounds great");
}

I expect it to give a different response ONLY if the var day is bad or terrible. Not for any other responses!

But the output is only

Thanks alot! It's my first time working with js so thank you for the quick response! — ksandur, Sep 16 '19 at 07:55
@DevsiOdedra there is no "in_array" in javascript. He can either use `indexOf` or `includes` in his case (or eventually `any`). `in_array` exists in php, not in javascript. — briosheje, Sep 16 '19 at 07:56

if (day == null || day == "bad" || day == "terrible") {
    document.write("How come?");
} else {
    document.write("sounds great");
}

You could use the switch statement.

switch (day) {
  case "bad":
  case "terrible":{ document.write("How come?"); } break;
  default: { document.write("sounds great"); } break;
}

So, in you case:

var day = window.prompt("How was your day? Describe it in 1 word!");
switch (day) {
   case "bad":
   case "terrible":{ document.write("How come?"); } break;
   default: { document.write("sounds great"); } break;
}

why the block statment in `case` statements part? – Nina Scholz Sep 16 '19 at 08:05
'cause I suppose he won't write just one line code. – Alessandro Sep 16 '19 at 08:07
[What do the curly braces do in switch statement after case in es6?](https://stackoverflow.com/questions/42480949/what-do-the-curly-braces-do-in-switch-statement-after-case-in-es6) I've always used it, I don't know if its a good practice, this could be a great question. – Alessandro Sep 16 '19 at 08:09
@Alessandro no, it won't be a great question. It's primarily opinion based and should be closed as such. – VLAZ Sep 16 '19 at 08:12
@VLAZ, it is not opion based, it is in this case superfluous, because of no local variables. – Nina Scholz Sep 16 '19 at 08:15
@NinaScholz coding styles might prefer it even if superfluous, however. Yes, it's *pointless* but since it is, you are free to require it as there won't be any change in behaviour. Coding style is all about that - requiring one of multiple options when there is no functional difference. And coding styles are just opinions, ergo, if a coding style would make you choose something, it's POB. – VLAZ Sep 16 '19 at 08:17
@NinaScholz I always close my code into braces, even when it's just one line, I think it's cleaner, especially because you can add new lines without lose scope variables and it's better to read code versioning diff. – Alessandro Sep 16 '19 at 08:21
