loadingremain
Loadingremain is a concept in software performance optimization and user interface design that describes tracking and communicating the amount of loading work still to be completed during an operation. It combines quantitative estimates with visual feedback to manage user expectations and perceived latency.
Origin and meaning: The term has appeared in web performance discussions in the 2010s and 2020s as
Concept and approach: A loadingremain system models the outstanding tasks—resources, API calls, or computations—as remaining work.
Implementation notes: Typical implementations instrument the resource loader to tag tasks, accumulate remaining work, and refresh
Applications and impact: Web and mobile apps use loadingremain to improve perceived performance and reduce frustration
