object is not iterable JavaScript

Question

I have an array of objects. But sometimes this is just a pure object and in such cases my loop fails. How do I prevent this.

   for(let singleItem of myObj){     // this works fine when I get an array of objects
            myArray.push({
                'Item 1': singleItem .Prop1.text,
                'Item 2': singleItem .Prop2.text
            })
        }

I get an error on for.....of when I have no array but just an Object with key values.

When I get the error, my object `myObj` will be like this.
{
   Prop1: { text: 'testvalue' },
   Prop2: { text: 'testvalue1' }
}

How do I ensure that I can fill my array myArray without any error?

You can check if myArray is object and then convert it to an array of one object.

for(let singleItem of Array.isArray(myObj) ? myObj : [myObj]){
