How to return multiple values of ZCO separated by comma from array of

Question

I work on angular 7 I face Issue : I can't separate values of ZCO by comma from array of object OriginCountry .

on component.ts

OriginCountry:any[]=[];
this.OriginCountry = this.partDetailsService.currentData.OriginCountry;
console.log("country origion" + JSON.stringify(this.OriginCountry) )

result returned from OriginCountry as below :

[{"CO":"zx","ZCO":"China","InfSrc":"FMD","TP":"Factory"},
{"CO":"zy","ZCO":"Japan","InfSrc":"FMD","TP":"Factory"}]

ON Component.html

<div *ngFor="let country of OriginCountry">
{{country.ZCO}}
</div>

Expected Result of ZCO as :

Japan,China
