Entirely different language when it comes to compile times, they were tremendously successful in the time-to-first-plot project. 1.6 was the release in 2021 that made the biggest difference, but with steady improvement since.

The big push now is to add everything needed so that making object/dylib code in Julia of comparable size to the usual systems languages is possible. The team has a track record of finishing what they start, I'm optimistic that they'll get that right as well.
