This isn't 4-digit, nor is it in JS, but might help you get an idea of achieving your aims. https://code.sololearn.com/cuumeZ0dI9iJ/?ref=app

num = '""+(1+Math.floor(9999*Math.random())); while (num.length<4) num = "0"+num; alert(num); [edit] :D replaced "print" by "alert"... too many Python at same time as JS ^^

Your solution require little adaptation: only the most left digit cannot be 0 ;)

Yes :) ... but mine solution is more efficient, as it require only one call to random() for generating the number, rather four in yours ;P

Yes, but you need this only for the most left digit, not the others ^^

Well you can tweak this when displaying the number.You could for instance check the length of the generated number. If it is a two digits number, you add two zeros before it. If it is a one digit, you add three zeros before... etc. that's how I personally see it.
