# React Performance Example
This is meant to be a minimal application to show the different between setting a state with plan JS objects, comparing the object before setting to state, and using Immutable.js to merge a new value into the old value before setting state.
## Running
```
yarn dev
```
## Summary
- Avoid passing objects as props when possible
- When you do pass objects as props, make sure the object source doesn't change unless it needs to
- Using `_.isEquals` is good if you want to just use JavaScript objects
- `mergeDeep` is good if you want to use Immutable.JS
