Julia's startup time is not short, but it's getting significantly shorter with every release. Right now, the startup overhead is only 0.13 seconds for me.

Some packages still take a while to load, e.g. for me to load the plotting pacakge and produce the first plot takes about 8 seconds (all subsequent plots in that session are fast). This is down from like 30 seconds last year.

One can also bundle heft packages like Plots.jl into their julia system image so they don't have to recompile all that machinery every time they restart julia.
