What is Prototype?

In JavaScript, objects also have one additional attribute: a pointer to another object. We call this pointer the object’s prototype.

Prototype allows you to create inheritance in JavaScript objects.

var man = Object.create(null);
defineProperty(man, 'sex', "male");

var yehuda = Object.create(man);
defineProperty(yehuda, 'firstName', "Yehuda");
defineProperty(yehuda, 'lastName', "Katz");       // "male"
yehuda.firstName // "Yehuda"
yehuda.lastName  // "Katz"

Object.getPrototypeOf(yehuda) // returns the man object

What is CLR?

The Common Language Runtime (CLR) is the virtual machine component of Microsoft’s .NET framework and is responsible for managing the execution of .NET programs.

A language like C# requires the .NET Common Language Runtime (CLR) to execute. Essentially, as an application that is written in C# executes, the CLR is managing memory, performing garbage collection, handling exceptions, and providing many more services that you, as a developer, don’t have to write code for. The C# compiler produces Intermediate Language (IL) , rather than machine language, and the CLR understands IL. When the CLR sees the IL, it Just-In-Time (JIT) compiles it, method by method, into compiled machine code in memory and executes it. The CLR manages the code as it executes.
