反应钩子：'TypeError：Object 不是函数'

Question

I'm using React version 16.13.1.

I'm getting 'TypeError: Object is not a function'

Here is my code (error message seems to think something is wrong with line 7):

import React, { useState } from 'react';
import fb from '../config/firebase';
import ProcessInput from './customHooks/processInput';

const DashBoard = ({ level, newUser }) => {

  const [val, bind] = ProcessInput('');

  const handleChange = (e) => {
    e.preventDefault();
  }

Here is my custom hook:

import { useState } from 'react';

export const ProcessInput = value => {
  const [val, setVal] = useState(value);

  return {
    val,
    setVal,
    bind: {
      val,
      onChange: event => {
        setVal(event.target.value);
      }
    }
  };
};

Thanks in advance for your help.

Answer 1

ProcessInput is returning an object, but you are destructuring it to an array.

Try this:

const {val, bind} = ProcessInput('');
