Why upgrade?

• realusername 8y ago
  Because if you don't upgrade, you are stuck with whatever version of React created at the time. You don't get stability & performance improvements, bug fixes, you can't potentially install some newer libraries requiring the new version. Not keeping up with upgrades is making the code rot slowly.

  Because sooner of later you'll have to. Upgrading frequently minimizes the delta.
