Hello,

i would like to use an array of objects but i can only create that array manually. I dont know how to create a bigger one ☹

My Code:

```auto
var test

let arrayOfObjects = [{},{}]

arrayOfObjects[1]['d'] = 777;

test = arrayOfObjects[1]['d'];

msg.logs = test

```

So i created an Array with 2 Objects. How do i create an Array with 100 Objects ? I could manually set 100 {}, but there must be a better way 🙂

I would like to go with an loop through that array.

The Payload what i want to get into that array looks that way:

If you do search 'create array of objects javascript' world wide, there is too many examples that nobody can't even count ...

```auto
let arr = []
let obj
for(let i=0;i<100;i++){
    obj = {}
    obj.someProperty = Math.random()
    obj.someOtherProperty = "Something"
    arr.push(obj)
}
//node.warn(arr)
msg.payload = arr
return msg;

```
