toggle boolean value equivalent for strings

Question

I know you can do the following in javascript to toggle a boolean in a one liner.

var toggle = false;
if(true) toggle != toggle;

but is this also possible with a string? i know it can be done by some if statements. But is it possible to do it in a oneliner? something like this:

var string_toggle = "CAT";
if(true) "CAT" = "ESP" || "ESP" = "CAT";

If it is not clear what i am asking let me know so i can improve the question.

Answer 1

You could use the ternary operator.

string_toggle = (string_toggle === "CAT") ? "ESP" : "CAT";

This effectively translates to:

if (string_toggle === "CAT") {
  string_toggle = "ESP";
} else {
  string_toggle = "CAT";
}
