useForm.js

import { useEffect, useMemo, useState } from 'react';

export const useForm = ( initialForm = {}, formValidations = {}) => {
  
    const [ formState, setFormState ] = useState( initialForm );
    const [ formValidation, setFormValidation ] = useState({});

    useEffect(() => {
        createValidators();
    }, [ formState ])

    useEffect(() => {

    }, [ initialForm ])
    
    
    const isFormValid = useMemo( () => {

        for (const formValue of Object.keys( formValidation )) {
            if ( formValidation[formValue] !== null ) return false;
        }

        return true;
    }, [ formValidation ])


    const onInputChange = ({ target }) => {
        const { name, value } = target;
        setFormState({
            ...formState,

            const [ fn, errorMessage ] = formValidations[formField];

            formCheckedValues[`${ formField }Valid`] = fn( formState[formField] ) ? null : errorMessage;

    return {
        ...formState,
        formState,
