Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library.

Node.js can be used for both front-end (handling user interface and interactions) and back-end (managing logic and data). The front-end uses HTML, CSS, and JavaScript frameworks, while the front-end uses Node.js framework, database, and cloud services. The focus is different (the front-end focuses on experience, the back-end focuses on functionality), the running environment is different (the front-end is in the browser, the back-end is on the server), and the tools are different (the front-end and back-end use different code compilation and packaging tool sets), although both use JavaScript , but with access to different APIs and libraries.

For front-end developers, the difficulty of learning Node.js depends on their JavaScript foundation, server-side programming experience, command line familiarity, and learning style. The learning curve includes entry-level and advanced-level modules focusing on fundamental concepts, server-side architecture, database integration, and asynchronous programming. Overall, learning Node.js is not difficult for developers who have a solid foundation in JavaScript and are willing to invest the time and effort, but for those who lack relevant experience, there may be certain challenges to overcome.
