Static in C#

Staic Member: You can access static member through the name of the class in which it is declared. E.g. className.StaticMethod();

You cannot access a static member through the instance of its class.

In C# there are no global methods. Static methods are similar to global method but with the advantage that they have access to local members. Equivalent of Static in VB.Net is Shared (and not Static which creates a variable that exists throughout the lifecycle of the program. Also it is not shared among different instance of the class.)

For static methods to access the non static methods of the same class, they must create instance of the class.

Static Constructor: It is guarnteed to run before the instance of the class is created. You cannot control when it will run though. No access modifiers are allowed on static contructors. You can use initializer instead of static constructor.

Static class: useful in creating small utility class holding static methods. Also it makes sure that you dont create instance of the class. Also it is a sealed class which cannot be derived.

Why there is semicolon at the start of a JavaScript function?

Very often while reviewing the code for my team, I will come across a semicolon at the start of JavaScript function as show below ; (function () { 'use strict'; ...and I often wondered what purpose it served. Guess what. It is an insurance to make sure your script works fine when all other scripts are merged together;  The leading ; in front of immediately-invoked function expressions (iffe) is there to prevent errors when appending the file during concatenation to a file containing an expression not properly terminated with a ;. So there you go. Now you know what that little semicolon is doing there in your code.

C# Performance Improvement - The Power of StringBuilder

 Often when we are wring code we don't think about performance and go with the default options available to achieve a task. String concatenation is one such scenario. If you are doing simple and few string catenations, then you can use the following result = string1 + string2; string1+= string2; result = String.Concat(string1,string2); String.Format and string interpolation are few other options.  However when you are performing large and repetitive  operation, string catenation can be expensive. Here is an example to prove the point.  As you can see it took 41 seconds to perform 100k string catenation. Now lets replace this with StringBuilder and see.  8 ms!!!!!! That is a massive performance difference. Hope you get the point. More info on StringBuilder can be found here https://learn.microsoft.com/en-us/dotnet/api/system.text.stringbuilder?view=net-7.0
