In Ruby, we are allowed to declare variables containing question mark like this: panelHidden? Is there any way to do this in JS? It gives me an error when I do this.

1This is not possible as it's invalid syntax – Dacre Denny Dec 26 '18 at 20:55

@DacreDenny Technically it is possible (ex `window['test?'] = 'weee'`), but you'd be forced to use array notation to access the variable, which is ugly – Taplar Dec 26 '18 at 20:58

The question mark character is not a valid JavaScript identifier character. – Pointy Dec 26 '18 at 20:59

@Taplar true, but I don't think that's what the author has in mind :) – Dacre Denny Dec 26 '18 at 21:01

@Taplar That's a property name, not a variable. (Although in Ruby, `panelHidden?` looks like method name indeed) – Bergi Dec 26 '18 at 22:39
