# `useCustomCompareEffect`
A modified useEffect hook that accepts a comparator which is used for comparison on dependencies instead of reference equality.
## Usage
```jsx
import {useCounter, useCustomCompareEffect} from 'react-use';
import isEqual from 'lodash/isEqual';
const Demo = () => {
const [count, {inc: inc}] = useCounter(0);
const options = { step: 2 };
useCustomCompareEffect(() => {
inc(options.step)
}, [options], (prevDeps, nextDeps) => isEqual(prevDeps, nextDeps));
return (
<div>
<p>useCustomCompareEffect with deep comparison: {count}</p>
</div>
);
};
```
## Reference
```ts
useCustomCompareEffect(effect: () => void | (() => void | undefined), deps: any[], depsEqual: (prevDeps: any[], nextDeps: any[]) => boolean);
```
