Don’t:

• needlessly construct Promises
• do anything with custom HttpHeaders here
• abuse any out of laziness
• manually unmarshal and marshal JSON when dealing with HttpClient
• use providedIn: 'root'

Do:

• deal with CORS issues on the server side
• use codefences when posting
• give methods descriptive names (as opposed to con)
• give proper types to all function parameters and return values
• follow coding conventions when it comes to capitalization: DialingCode is a class, not an object member name
