Go Design Patterns - Generator Pattern and Observer Pattern - Part Two

#tensorprogramming #golang #designpatterns

In this tutorial, we take a look at the Generator pattern and the Observer pattern. We create a Generator function and then use the observe pattern to create a means to listen to it as a subject with multiple observers.

Very informative video! :')
Btw, you meant type assertion and not casting(type conversion) which is used for such situations where you had to wrap your concrete type into an interface and want your concrete type back. (This info might help others so putting it here.)

We are waiting for new videos on the patterns.
Tensor, you're cool.

Using two communicating threads inside a thight loop seems like an anti pattern to me. A better approach to generators in Go is a function that returns a function that captures state of the returning function. That way you can call the returned function without parameters multiple times and it will still yield different values.

@tensorprogramming what VSCode extension do you use to show the type under the cursor? Sorry if this already got explained.
