Description

Most frontend apps feel slow without throwing a single error. That's because performance bugs don't appear in the console - they hide in reflows, repaints, and layout recalculations. If you're preparing for senior frontend interviews, this is not optional knowledge. Understanding how the browser builds the DOM, CSSOM, render tree, and triggers reflow vs repaint is what separates mid-level from senior developers. No errors ‡ good frontend performance. Performance should never be ignored. #frontendinterview #weboptimization #JavaScript web-development #perfmatters #webperf #frontend #frontenddevelopment #performance #
