Question 181956 in Javascript Question posted in
A very good W3school tutorial can be found here.

JAVASCRIPT: Class method returns a promise. But I want it to return the resolved result. How do I rewrite the class method?

This is my class.

export MyClass {
    
    private readonly ServiceEndpoint: string = 
    "/xxx/xxx.DMS.UI.Root/Services/ConfigurationAPI.svc/";
    
    
    public async GetAllCompanies(): Promise<CompanyDto[]> {
    return fetchAsync(
        `${this.ServiceEndpoint}Company`,
        'GET'
        )
      .then(value => value.GetAllCompaniesResult);
  }

}

Presently, this method returns a Promise <CompanyDto[]>. How do I rewrite it so that it returns only the result CompanyDto[]?

    I think you are missing await keyword here. Can you please try using await.

    export MyClass {

private readonly ServiceEndpoint: string = 
"/xxx/xxx.DMS.UI.Root/Services/ConfigurationAPI.svc/";


public async GetAllCompanies(): Promise<CompanyDto[]> {
   let result = await fetchAsync(
    `${this.ServiceEndpoint}Company`,
    'GET'
    )
  .then(value => value.GetAllCompaniesResult);
  return result;

    }

    }

    Just use await. Make sure your types are correctly inferred.

    export MyClass {
    
    private readonly ServiceEndpoint: string = 
    "/xxx/xxx.DMS.UI.Root/Services/ConfigurationAPI.svc/";
    
    
    public async GetAllCompanies(): CompanyDto[] {
      const result = await fetchAsync(
        `${this.ServiceEndpoint}Company`,
        'GET'
        );
      
      return result.GetAllCompaniesResult;
    }

}
