Why Lighthouse Dropped Time to Interactive (TTI) and What Replaced It

This article explains why Lighthouse removed the Time to Interactive (TTI) metric after version 10, describes how TTI was calculated, discusses its inaccuracies, and introduces the more reliable replacement metrics such as Total Blocking Time (TBT), First Input Delay (FID) and Interaction to Next Paint (INP) for assessing web performance.
