Inheritance is discouraged in React code and should always be avoided for components. Composition solves the same problem in a way that is much easier to maintain.
Consider this:
-
You'd have to remember to call
super
from lifecycle hooks, or component would break in a weird way. -
If React Redux starts to use a new lifecycle hook in its internal implementation, your existing code might break even if it worked before, because you might have been forgetting to call
super
. -
Name clashes. What if you name your method
handleChange
? You're going to overwrite my method. Oops! -
What if every utility component behaved this way? We can't have more than one base class.
In short, inheritance brings a bunch of problems, and doesn't have any advantages to composition in case of React components. Don't use it.

Thanks for a good explanation! Will avoid using it in such way!
Just wanted to make using of connectors more transparent than 'connector(select)(Component)' calls. But I think that's wrong way:)

If you want a neater syntax you can use ES7 decorators proposal implemented by Babel.
Note that it's experimental and may change.
@connect(select)
export default class MyComponent { }
from react-redux.
Thanks, I've already noticed that in examples, but still want to avoid using experimental ES7 parts.
