Tips on delaying the return of the Angular compiler until the subscription is complete

I'm facing an issue with a function that needs to return a value while containing a subscription. The problem I'm encountering is that the return line is being executed before the subscription ends,

testFunc(){
let objectType;
          let moduleId;
          objectType = valueAsString.split('|');
          objectType = objectType[0];
          this.layoutService.moduleIdByType(objectType)
            .toPromise().then(data => {
              moduleId = data;
            });
          return { IsById: true, LinkedModule: moduleId };
}

Within this code snippet, moduleIdbytype is altering the value of the moduleId variable. I need to ensure that I only return after the subscription has completed and modified the variable's value.

To handle the subscription in your testFunc(), you can convert it to an asynchronous function and use await for the subscription.

async testFunc(){
 let objectType;
 let moduleId;
 objectType = valueAsString.split('|');
 objectType = objectType[0];
 const moduleId  = await this.layoutService.moduleIdByType(objectType)
 .toPromise();
 return { IsById: true, LinkedModule: moduleId };
}
