I am looking to create a function that will generate numbers sequentially with each execution. This is important for me as I need to establish an order for my items in mongoDB using JavaScript. Can anyone provide guidance on how to write a JS function that will produce sequential numbers each time it is run? For example, the function should output 1 when first executed, then 2 on the next run, and so forth.
const increment = (function() {
let count = 0;
return function() {
return count++;
}})();
console.log(increment()); // 0
console.log(increment()); // 1
console.log(increment()); // 2
