Presentational/Container components: are these terms misleading?

Presentational/Container have long been suggested as terms to describe two different classes of React components. However I think these terms are a bit deceptive, and don't accurately represent the differences between them:

Presentational components

  • can "contain" other components, thus they also act as containers
  • not concerned merely with "presentation" (in the same way that CSS is)

Container components

  • do more than simply "contain" other components. Containing other components is not what makes them unique
  • have an active role in accessing and mutating the state of your application. This is what differentiates

  • 4 wrapped packages of soba noodles. There are usually 3 in a big package
  • 1/2 cucumber
  • 1 red pepper
  • 3 medium carrots
  • 2/3 cup chopped cilantro
  • 2/3 cup chopped thai basil

Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:
