Why is this forEach code snippet invalid in AngularJS?

Question

Here I have a generic calculation function.

private calculateTotal(order: InventoryOrder):number{
  let total = 0.0;
  if(order && order.currentInventory){
    order.currentInventory.forEach(x =>{
      console.log(x.quantity);
      console.log("helloworld");
    }  //error appears here<- "," expected.
  } return total;
}

I tested very similar code at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach

    const array1 = ['a', 'b', 'c'];
    
    array1.forEach(element => {
                    console.log(element);
                    console.log("helloworld");
                              });

// expected output: "a"
// expected output: "b"
// expected output: "c"

Any idea what's going on?

You are missing a closing parenthesis after the closing bracket after "hello world" — Andy

I just ran the code locally and it worked fine for me 🤷🏽‍♂️ — Pytth

as an aside, you can try using the angular foreach loop angular.forEach(order.currentInventory, function(value, key) { // test it here }); — Kinglish

I went through your code again and there was a missing bracket, I would highly suggest you use an editor such as VS code or phpstorm that will highlight these issues for you straightaway. Thanks.

Yep! That's correct as outlined by the folks above. I appreciate you taking the time to do that. Marked correct :) - I'll assume you meant parenthesis instead of bracket ;)
