Difference Between useState and useEffect in React
Hooks are commonly used in React, particularly useState and useEffect. This section explains their differences.

useState
useState is a hook that updates the state of a component. It takes an initial value as an argument and returns an array containing the current state and a function to update it. The function to update the state can be used both in the component's state and in the render method.

useEffect
useEffect is a hook that executes a function after the initial render and whenever the component re-renders. It takes two arguments: a function that contains the code to be executed and an array of dependencies. When any of the dependencies change, the function is executed again.

Example
The transcript provides an example to illustrate the difference between useState and useEffect. A function called 'start' is created using both useState and useEffect.

When 'start' is called using useState, the state is updated, and the value is rendered. When 'start' is called using useEffect, the load function is executed, and the page is loaded.
