It is now time to have another user test out your prototype and provide feedback that you can use to tweak your logic flow and program features. This is an important part of the process because a second set of eyes can give you a more objective view when creating a program. Step 3: ...
On the other hand, you can also use pseudocode, which is a simplified version of code written in plain language. It outlines the algorithm's logic without getting into the syntax of a specific programming language. Pseudocode is useful for planning and communicating the algorithm’s structure. ...
That’s largely because the reactive-forms approach doesn’t do away with the template, but instead removes most of the logic away from the template and into the component. This is where things start to take a left turn from the techniques examined in the previous pair of...
Second, certain problems lend themselves better to certain programming approaches or environments; case in point, the F# language frequently “makes more sense” to those with a mathematical background and makes it easier sometimes for them to write certain kinds of code. Suc...
Conceptually, it looks a lot like the previous, non-Mongoose version, but there’s a really important, if subtle, change: logic about Person is now being more localized to the Person model (and Mongoose’s own persistence implementation). ...

More generally, it’s a very common pattern to check for null before invoking a member in order to avoid a System.NullReferenceException (which almost always indicates an error in the programming logic). Because of the frequency of this pattern, C# 6.0 introduces the “?.” operator known ...
