In this section, you'll learn how to use the simple property type validators available in the PropTypes object. Then, you'll learn how to accept any property value as well as make a property required instead of optional.
Let's take a look at validators that handle the most primitive types of JavaScript values. You will use these validators frequently, as you'll want to know that a property is a string or that it's a function. This example will also introduce you to the mechanisms involved with setting up validation on a component. So, here's the component itself; it just renders some properties using basic markup:
import React, { PropTypes } from 'react';
const MyComponent = ({
myString,
myNumber,
myBool,
myFunc,
myArray,
myObject,
}) => (
