Battery.js is a JavaScript library designed to provide developers with an easy way to access and utilize battery status information from web browsers. It leverages the Battery Status API to retrieve data such as battery level, charging status, and remaining charging or discharging time, allowing developers to create applications that can respond dynamically based on the device's power state.

About Battery.js
Battery.js was a JavaScript library that provided developers with tools to access battery status information from web browsers. It utilized the Battery Status API to gather data such as battery level and charging state. The library aimed to help developers create applications that could adapt to the device's power conditions. While specific details about its creators or founding year are not widely documented, it emerged as part of efforts to enhance web applications' interactivity and responsiveness regarding device power management.
Strengths of Battery.js included its ability to easily access battery status information and improve application responsiveness to power conditions. Weaknesses involved reliance on the Battery Status API, which faced privacy concerns leading to reduced support in some browsers. Competitors included other libraries or solutions that addressed device power management, though many relied on similar APIs and faced similar limitations due to browser support changes.
