Make fields '𝗿𝗲𝗮𝗱𝗼𝗻𝗹𝘆' when exclusively assigned in the constructor!

A field set only in a constructor without the readonly modifier may lead to ambiguity in its intended use.

Marking such fields as readonly enhances clarity about their purpose.

The readonly modifier prevents unintentional alterations by future maintainers.

However, there are some 𝗲𝘅𝗰𝗲𝗽𝘁𝗶𝗼𝗻𝘀:

→ Fields declared in classes marked with the Serializable attribute.

→ Fields declared in partial classes.

→ Fields with attributes are ignored.

→ Fields of type struct that are not primitive or pointer types are also ignored because of possible unwanted behavior.

𝗚𝘂𝗮𝗿𝗱 is a conditional statement to perform early input validation and detect problematic states, mitigating potential execution errors within a method.

The 𝗴𝘂𝗮𝗿𝗱 𝗰𝗹𝗮𝘂𝘀𝗲 runs before the main code, quickly checking if specific conditions are not met and 𝗳𝗮𝗶𝗹𝗶𝗻𝗴 𝗳𝗮𝘀𝘁 if necessary. It guards the rest of the code.

✅ By checking for invalid input or problematic states at the beginning code becomes less cluttered and easier to follow, enhancing both code 𝗿𝗲𝗮𝗱𝗮𝗯𝗶𝗹𝗶𝘁𝘆 and 𝗺𝗮𝗶𝗻𝘁𝗮𝗶𝗻𝗮𝗯𝗶𝗹𝗶𝘁𝘆.
✅ This technique is highly effective for preventing deep conditional nesting, making the logic flow clearer and more transparent.

Do you use 𝗚𝘂𝗮𝗿𝗱𝘀 & 𝗙𝗮𝗶𝗹 𝗙𝗮𝘀𝘁 techniques in your code? 👇

🚀 In LINQ queries, the order in which you apply operations can affect performance. If you filter a collection using 𝗪𝗵𝗲𝗿𝗲 before sorting it with 𝗢𝗿𝗱𝗲𝗿𝗕𝘆, you reduce the number of items that need to be sorted. Sorting is generally more computationally expensive than filtering, so this can result in significant performance benefits, especially for larger collections.

🔥 This approach enhances performance because we're sorting a smaller subset of the original data.

Here are some tips to help you enhance the performance of your SQL queries.

Here is first a jQuery AJAX example showing how to make an AJAX call in jQuery:

var jqxhr = 
    $.ajax({
       type: "POST",
       url: "/theServiceToCall.html",
       data: {
           name : "The name",
           desc : "The description"
        }
    })
    .done  (function(response, textStatus, jqXHR)    { alert("Success: " + response); })
    .fail  (function(jqXHR, textStatus, errorThrown) { alert("Error"); })
    .always(function(jqXHROrData, textStatus, jqXHROrErrorThrown)     { alert("complete"); })
    ;
