How to Play a Video from Local Storage in JavaScript

In today's digital landscape, user experience is key. One simple yet powerful feature you can add to your web application is the ability to pause a video and resume it from where the user left off. This is especially useful for content that may take several sittings to consume. In this guide, we will guide you through the process of achieving this using JavaScript and local storage.

The Problem: Play Video from Paused Position

You might want to create a video player that remembers the last position where a user paused the video. This not only enhances user experience but ensures they don't miss any content. The challenge we will address is how to save the current time of the video in local storage when paused, and then retrieve and play that time when the user returns.

Current Setup

You have a basic HTML setup that includes a video element and a play/pause button.

Let’s break down the solution into clear steps:

Step 1: Update Video Play/Pause Function
