React PropTypes验证arrayOf必需的元素不能正常工作

import PropTypes from 'prop-types';

function validateArrayOf(requiredType) {
  return function (props, propName, componentName) {
    const propValue = props[propName];
    if (!Array.isArray(propValue)) {
      return new Error(
        `Invalid prop ${propName} supplied to ${componentName}. Expected an array.`
      );
    }

    for (let i = 0; i < propValue.length; i++) {
      if (typeof propValue[i] !== requiredType) {
        return new Error(
          `Invalid prop ${propName}[${i}] supplied to ${componentName}. Expected ${requiredType}.`
        );
      }
    }

    return null;
  };
}

// 使用示例
MyComponent.propTypes = {
  arrayOfStrings: validateArrayOf('string'),
  arrayOfNumbers: validateArrayOf('number'),
};
