JavaScript Design Patterns - Command Pattern

JavaScript Design Patterns - Command Pattern

JavaScript Design Patterns - Command Pattern. Command pattern is a data driven design pattern and falls under behavioral pattern category. What's the command pattern. Why the command pattern is important. How to implement the command pattern in JavaScript. When to use the command pattern. The idea of the command pattern is to create an abstraction between the operations an object can do, its commands, and the actual commands themselves

The command pattern is probably my favorite design pattern, because of all the fun things you can do with it. The idea of the command pattern is to create an abstraction between the operations an object can do, its commands, and the actual commands themselves. This makes it really easy to combine together or chain different commands without having to change the code. The program can dynamically chain and combine these actions. The best part is since each command is its own object you can easily implement and undo function for each command and make a set of undo-able actions.
