create random 4 digit number js

var val = Math.floor(1000 + Math.random() * 9000);
console.log(val);

javascript 5 digit random number

var min = 10000;
var max = 90000;
var num = Math.floor(Math.random() * min)) + max;

here you can increse the min and max value this is for 5 digits 


or this
Math.floor(Math.random()*90000) + 10000;

javascript get a random number with 6 digits

Math.floor(100000 + Math.random() * 900000);

generate random 6 numbers in javascript

console.log(Math.floor(100000 + Math.random() * 900000));

javascript random 4 digit number

var seq = (Math.floor(Math.random() * 10000) + 10000).toString().substring(1);
console.log(seq);

generate random 6 digit number javascript
