Question Title GDB
Question Description
In a programming world, Lambda Expression (i.e. lambda function) is essentially a block of code that can be assigned to a variable, passed as an argument, or returned from a function call. It has been part of several programming languages like Smalltalk, Lisp, Ruby, Scala, Python, Java and C# etc. for quite some time.

In context of C# programming, a lambda can be used instead of an anonymous method/function where we do not need to provide access modifier, return type and even name of the method. For example, the following anonymous method checks if a student is teenager or not:

Listing 1: (anonymous method in C# to check if a student is teenager or not)

delegate(Student std) {

return std.Age > 12 && std.Age < 20;

}

While the same functionality can be achieved by using lambda as;

Listing 2: (checking if a student is teenager or not using lambda in C#)

std => std.Age > 12 && std.Age < 20;

Here, we can see that the code has been shortened (i.e. writability increased). However, it makes the code relatively difficult to understand as “std” in listing 2 is ambiguous (i.e. readability decreased). But what about Reliability?

Being a programming language expert, you are required to compare both approaches (i.e. code written with/without lambda) and state which one is better in terms of Reliability in C# programming language.

Anonymous Method Limitations

It cannot contain jump statement like goto, break or continue.
It cannot access ref or out parameter of an outer method.
It cannot have or access unsafe code.
It cannot be used on the left side of the is operator.

Looking at these VMs at the highest-level, the differences between the CLR and JVM seem almost negligible. However, in many (if not most) cases, the differences at the VM-level mirror the key differences between the languages that use them. Because of the way these VMs, and their corresponding languages, were built, each functions slightly differently in order to provide the functional capabilities that their creators wanted to provide.

What do you think about the differences between the CLR and JVM? Will you choose your next programming language based on which VM it uses? Let us know in the comments below!

I think it will be really hard to create one single language all could and importantly would used by all.

All software today could be written in assembly, but it would mean getting up a website could take 6–12 months and probably cost a few million….

If we ever had a single language all would use, that language would need to do 5 things really well.

And while I have seen languages that can do 2–3 out of 5, I have never seen language that can do all 5.

Have really low system overhead and compile to machine code on any platform.

Have terse easy to learn syntax.

Support all the programming paradigms. Procedural, object oriented & functional.

Have really large ecosystem 3rd party packages and great developer tooling for solving any problem in any industry.

Have highly performant bridge to call directly(no REST/JSON/SOAP/XML mess…) to any language. Even if we decided today to rewrite all software to this new miracle language it would take 10 years to modernize all the legacy stuff so integration needs to be seamless.
