Faster Angular Applications
summary
Runtime slowdowns come from unnecessary recomputation, not the framework: switching to OnPush change detection plus isolating input events prevents whole-tree checks, using Immutable.js avoids copying large lists, and replacing template calculations with a pure pipe plus memoization (lodash or decorator) moves repeated Fibonacci-like business work into a cache. End-to-end Benchpress runs show about 3× speedup and initial 1,000-item render drops from ~9.5s to ~3s, with simple refactors and targeted tools.
