How to measure JavaScript performance (aside from page load time)

There seem to be a lot of tools to check how much time it takes to load a specific script, but what about performance impact on the user's machine? Does anyone know of any tools to see the CPU demands of a specific script, especially on mobile?

As I write apps, I feel like I'm trying my best to cut down on unnecessary logic, but I have a hard time knowing how I'm doing — and whether the end user's experience will be smooth — with no CPU benchmarks or guidelines.

You can simply use profiling browser tools (like in Firefox right click-> Inspect element and choose performance tab).

Or you can measure your functions performance by using High Resolution Time API

There are some tools out there but if you are using chrome you already have a great one installed: https://developer.chrome.com/devtools/docs/timeline
