Async problems using "getUserInventoryContents"

[MrKirby]

I am having issues with calling this function. I think it has something to do with the function waiting a little while. I have searched for callback etc. on the internet and I found a lot but I have no clue how to use them on the code...

 

Question

How do I use sync callback on the function: "getUserInventoryContents"

 

This is what I have now:

manager.getUserInventoryContents(config.accounts.steamid64[i],753, 6, true, (err, inventory) => {
    if (err) {
        console.log(err);
        return;
    } else if (err == null) {
    //The rest of the code				

I thought that this would work... I am not the best in node, basically just started... but hope you could help me

Synchronous I/O functions are contrary to Node's paradigm and so aren't supported. Or is that not what you're asking?

Thanks for the quick response, but it is not what I am looking for, I think.

Whenever it is busy 'getting' a user's inventory, it should freeze a code block (like a normal callback function could do).

But I have no clue on how to run a callback on the "getUserInventoryContents" functoin. 

 

EDIT:

var j = 10;
for(var i=0;i<j;i++) {
console.log("testing... " + i)
manager.getUserInventoryContents(config.accounts.steamid64[i],753, 6, true, (err, inventory) => {
	if (err) {
		console.log(err);
		return;
	} else if (err == null ) {
						
        console.log("Inventory length bot " +inventory.length+" | steamID "+ config.accounts.steamid64[i]);
        //etc. etc.

This will output: 

testing... 0
testing... 1
testing... 2
etc.
testing... 9
Inventory length bot 100 | steamID 12345678901234567890 //random ID 
Inventory length bot 100 | steamID 12345678901234567890 //random ID 
Inventory length bot 100 | steamID 12345678901234567890 //random ID 
etc.
Inventory length bot 100 | steamID 12345678901234567890 //random ID 
Inventory length bot 100 | steamID 12345678901234567890 //random ID

Now, how can I make it output this:

testing... 0
Inventory length bot 100 | steamID 12345678901234567890 //random ID 
testing... 1
Inventory length bot 100 | steamID 12345678901234567890 //random ID 
testing... 2
Inventory length bot 100 | steamID 12345678901234567890 //random ID 
etc.

Thanks in advance

You could perhaps use the async module.
