WakeUpTimes App

We will build a simple web application to suggest "wake up" times based on calculating sleep cycles from when you fall asleep.

A web application is a software application that runs on a web server and is accessed through a web browser. Unlike traditional desktop applications, web applications do not need to be installed on a user's device and can be accessed from anywhere with an internet connection. Web applications can be used for a variety of purposes, from simple tools like calculators and to-do lists to complex systems like online marketplaces and social networks.

HTML, CSS, and JavaScript are the three core technologies used to build modern web applications. HTML is used to structure and define content on a web page, while CSS is used to style and layout the content. JavaScript is used to add interactivity and dynamic behavior to a webpage, such as animations and user input handling. Together, these technologies form the backbone of the web, allowing developers to create rich, responsive, and engaging applications that can be accessed from anywhere in the world with an internet connection. In this tutorial lesson, we will touch all three of them.

A sleep cycle is the period of time it takes to complete all stages of sleep, from light to deep sleep and back to light sleep. A good night's sleep involves completing 5 to 6 of these cycles, which typically last around 90 minutes each. By calculating sleep cycles, our WakeUpTimes app can suggest wake up times that align with the end of a sleep cycle and help users wake up feeling refreshed and energized.
