#ASKTHEINDUSTRY 14: What can I do to lower my JavaScript parse times today?

This one is incredibly simple, yet not quite easy to do.

Here are my 5 strategies:

1. Ship less JavaScript
2. Use less transpiled code
3. Split your code in separate bundles
4. Enable a tree shaking and dead-code elimination build step, if you’re bringing in a lot of dependencies
5. If using a modern framework, see if Ahead of Time compilation is available (AoT)

That’s it.
