Adding an Array to an Array in Angular

Question

So I have a db document that holds some string values in an array, I want to push just the array from every entry into an array in the application for usage later, But I can see the array fine on the fetch, and when I iterate it but my "Global array" is staying empty can someone explain why?

specialDates : Specialdates[] = [];
specialRange: any[] = [];

this.specialDates.forEach(ag => {      
//ag,range -> I can see fine
   this.specialRange.push(ag.range);
//this.specialrange -> Stays empty 
});

Array looks something like the following:

1205,1206,1207,1208

What is wrong with this approach?

Reason for doing this is because the documents have 2 fields minimum: EG -> ID/Array

And I just need the array

can you try this and see what does it display? this.specialRange = [...this.specialDates] — 31piy
