Setinterval Not Working As Expected With Counting Function

I know this may be an easy answer, but I am having trouble using my function with setInterval. Here is what I have so far: function countUp(n) { console.log(n++); } setI

Solution 1:

You need to increment a variable in the enclosing scope of the function:

var n = 10;

functioncountUp() {
    console.log(n++);
}

setInterval(countUp, 1000);

Update: Here's a strategy that doesn't involve a global variable:

functioncountUp(start) {
    returnfunction() {
        console.log(start++)
    }
}
setInterval(countUp(10), 1000);

As I noted, the counter just needs to be in the enclosing scope, not the global scope. So passing it into a function that can reference it in a closure will work fine here.
