Agreed. Julia's combination of REPL + JIT + Revise.jl can feel like magic. The compiler automatically detects changes to your source code and provides hot-code reloading of fully optimized machine code, in the blink of an eye!

Also, it's worth emphasizing that the user experience of Julia has been improving greatly, even in just the last 3 years. Julia 1.9 introduced caching of native code [1], and now at Julia 1.11 the time-to-first-plot in a new Julia process is typically less than a second.

Having said all this, Rust is an absolutely fantastic language too, and might be preferred for large-scale software development efforts where static analysis is prioritized over an interactive development workflow.
