  • Are you trying to write regex that checks if the first character of a string is `!` or not? – Nisarg Shah Aug 13 '17 at 13:32

    What have you tried? This is not how SO works. You show your attempt and people provide fixes. – Script47 Aug 13 '17 at 13:34
  • i know how to check the FIRST CHAR IN STRING but my question is - how can i check the (!) exclamation char ... i find only things for A-Z or number but not ONLY for that – Mr.Butterverleih Aug 13 '17 at 13:56

//using regex
let a = "!variable";

let test = /!/.test(a);

if (test) console.log("there is \"!\" somewhere in \"a\" variable");

//or not using regex

let char = a.split("", 1)[0];

if (char == "!") console.log("first letter is \"!\"");

The second part takes first letter and logs message if it is "!" , first part tests whole string in order to find "!". I'm not sure if there is a way to check that first letter is "!" using regex.
