  1. “Speaking about JavaScript frameworks at such a time as this can never be complete if nothing is said about the React framework created and maintained by the team at Facebook.”

    React is not a framework, it’s a UI-library for creating re-usable components.

    1. You’re technically right, but it’s a meaningless distinction IMO. If you’d like to write a post for the blog explaining why it’s not a meaningless distinction, I’d be happy to publish it.

  2. Why we call react a framework ?
    Is it because it became so popular, that it replaced angular in many real world projects…
    angular is framework, so we call react also a framework

  3. Appreciate the way this article explains. I have been searching for “how to write pure components wo using class”. hardly any articles available.. This is very well articulated.
    Thanks.
