# 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
