JavaScript Start-up Performance

I published a new Medium article on JavaScript Start-up Performance. In it, I dive into some of the largest reasons modern web apps can be slow to boot-up, like time spent parsing and compiling code.

This can be a challenge for not just our application logic, but also a transitive issue for modern JavaScript frameworks and libraries. This post walks through causes for slow start-up, how to measure using some of the latest additions to Chrome DevTools and what you can do to make your app start up faster.
