On the better with time point, see here. If you want to read lots more about this, search “time to first plot,” mentioned above, which is a shorthand for this issue (plotting packages are notorious for long compilation times).
But I would also encourage you to explore other workflows. I come from bioinformatics, where everything is a script, so I totally get the inertia. But now I use the REPL and Atom, for most development, and only write scripts for long running precesses where compile time is a tiny fraction. Think about it this way: when you’re coding interactively, use the interactive tools.
A couple workflows have been mentioned here, there are also great ways to use Atom or VS code as development environments. I usually start up Julia first thing, run a script that loads my packages (esp. Revise.jl), get a cup of coffee, and then don’t worry about compilation for the rest of the day.
