`js
import React from "react";

`

$3

`js
import React from "react";
import { useDeepCompareMemo } from "use-deep-compare";

}
`

// create imperative methods
}), [object, array]);

return

;
}
`

To receive eslint warnings about missing array dependencies, just like for standard useEffect, useCallback, useMemo, ... hooks - extend you eslint config as follows:

`json
{
"rules": {
// ...
"react-hooks/exhaustive-deps": ["warn", {
"additionalHooks": "(useDeepCompareEffect|useDeepCompareCallback|useDeepCompareMemo|useDeepCompareImperativeHandle|useDeepCompareLayoutEffect)"
}]
}
}
``
