Introduction
null is a fundamental concept in many programming languages. It is ubiquitous in all kinds of source code written in these languages. So it is essential to fully grasp the idea of null . We have to understand its semantics and implementation, and we need to know how to use null in our source code.
Run-time Implementation
Before discussing the meaning of null, we need to understand how null is implemented in memory at run-time.
Performance
As we learned in the previous section, operations involving null are extremely fast and easy to perform at run-time.
Reference vs Value Types
So far we assumed working with reference types. The reason for this is simple: null doesn't exist for value types.
Meaning
Suppose we have a type person with a field emailAddress. Suppose also that, for a given person which we will call Alice, emailAddress points to null.
When to Use null (And When Not to Use It)
The basic rule is simple: null should only be allowed when it makes sense for an object reference to have 'no value associated with it'. (Note: an object reference can be a variable, constant, property (class field), input/output argument, and so on.)
