Course of Behavioral Design Patterns

💸 First lesson available without registration 💸

What will you learn in this Behavioral Design Patterns course?

When solving a request or algorithm, we may encounter certain challenges in finding a good design. Well, there are problems that are very common, and we can use the behavioral patterns that we see in this course.

In each example, we see the implications they have at the level of SOLID and maintainability, before and after applying them, and we analyze their advantages and disadvantages, as well as alternatives and similarities with other patterns.

During the course, we elevate certain patterns to macro design and see the utility of combining several patterns.

Learn to know when to apply Behavioral Design Patterns and understand the advantages and trade-offs they involve using them! 💪
