[JS Pattern] Container / Presentational Pattern

Presnetational Component:

A presentational compoentn receives its data through props. It's primary function is to simply display the data it receives the way we want them to, including sytles, without modiying that data.

 

Container Component:

Container component is to pass data to presentational component. Since they don't render anything themselves, they usually do not contain any styling either.

 

Hooks

In many cases, the Container / Presentational pattern can be replaced with React Hooks. The introduction of Hooks made it easy for developers to add statefulness without needing a container component to provide that state;

 

Pros / Cons

Pros: 

1. Separation of concerns
2. Resuable
3. Modify presentational component is easy
4. Testing is easy

Cons:

1. With React Hooks, this pattern can easily be an overkill in smaller sized application
