Google has introduced a new method for running JavaScript to enhance webpage responsiveness, especially regarding the Interaction to Next Paint (INP) metric, a replacement for First Input Delay (FID). INP is set to become a Core Web Vital metric in March 2024. To score well on INP, a webpage must be highly responsive to user interactions. Long-running JavaScript scripts, known as Long Tasks, often hinder INP scores by blocking user interactions. Google's solution, called ""scheduler. yield,"" allows long tasks to pause and yield to user interaction tasks, improving webpage responsiveness. While existing coding workarounds have been developed, they often need more effectiveness. Google is testing this feature and seeking feedback through an ""origin trial"" before its official release. Web developers should monitor this development, as it can improve webpage performance and user experience.
