Answer 4

'#x27; is a valid vaiable identifier name in JS, mostly used as JQuery base function library, but you can use it ( if bit using JQuery ) as any custom variable. So, you can do:

var $ = [ 1, 2, 3, 4, 5 ];
var x = 2;
alert( x-$[x] );

And you'll get an alert box with the output of '-1', as result of '2-3'...

Answer 5

In JavaScript, it denotes the usage of JQuery.
