What Do You Think About Immutable Data?

Miklos Bertalan - Feb 14 '19 - - Dev Community

A few things are becoming de-facto solutions in JavaScript with a lot of tutorials but without much discussion about the practical benefits and reasons. The goal of this series is to talk about these topics.

The rules:

  • Speak about the whys, not the hows. It's okay to include a few favorite libs and patterns but it should not be the main focus of your comment.

  • No Googling! I am interested in Your opinion, experience, anecdotes, and gut feelings.


This week's topic is Immutable Data

  • Why is it so popular?

  • When do you use it? Does it belong to the back-end, the front-end or both? Do you use it together with specific patterns or tech stacks?

  • Do you use it because it's your stack's best practice? Do you consciously choose a stack the relies on immutable data?

  • Did you ever have issues with mutable data?

  • Whatever pops into your mind about Immutable Data.

All comments are welcomed, there is no wrong answer!
