This (including the commented line) fixed all my issues and returned the correct veri. My question is why the first method I mentioned acted in the way that it did.
As mentioned above, this attribute is used to specify the source class. It also güç be used to specify custom methods to run on before or after the mapping process.

In this example we are using the object spread syntax and template literals, but you could also explicitly rewrite the properties:
We use technologies like cookies to store and/or access device information. We do this to improve browsing experience and to show (non-) personalized ads.
It eliminates the need to use reflection to map objects and makes it much faster in runtime. It provides compile-time safety checks and ease of use by leveraging extension methods.
Another one, which might not seem very practical, is when you website want to simulate some requests coming in:
Like many other helper operators in RxJS, behind the scenes pluck is simply reusing the map operator, passing it a function to grab the appropriate property:
