You have already asked this question [here 
before](https://forum.dlang.org/thread/nvaiwzvcrahnwziorazc@forum.dlang.org). The spec outlines the meaning of equality and identity expressions here:
- https://dlang.org/spec/expression.html#equality_expressions
- https://dlang.org/spec/expression.html#identity_expressions

You should try to reference the spec when you don't understand 
something. It's essentially the best resource for learning about 
D's finer points.
