I just want to know which of the following approach is recommended in terms of the performance and best practices. Is there any performance difference?
if (objA.objB.objC.objD.objE != null)
{
objX.var1 = objA.objB.objC.objD.objE.prop1;
objX.var2 = objA.objB.objC.objD.objE.prop2;
objX.var3 = objA.objB.objC.objD.objE.prop3 + objA.objB.objC.objD.objE.prop4;
......
......
}
or
var objonlyE = objA.objB.objC.objD.objE
if (objonlyE != null)
{
objX.var1 = objonlyE.prop1;
objX.var2 = objonlyE.prop2;
objX.var3 = objonlyE.prop3 + objonlyE.prop4;
......
......
}

C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr. Stroustroupe.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
C is more difficult to learn than JavaScript, but it's a valuable skill to have because most programming languages are actually implemented in C. This is because C is a “machine-level” language. So learning it will teach you how a computer works and will actually make learning new languages in the future easier.
The second one is better because you never know what's hiding behind a '.'. It could be a database call or some other expensive operation.
