Julia's tongue is described as
it is faster than other scripting languages, allowing you to have the
Python / MATLAB / R fast development while also producing code
fast like C / Fortran
by Christopher Rackauckas. It continues by displaying the assembly code generated for various pieces of code. These seem well optimized. Among the other examples of Julia's effectiveness, let us mention the fact that several linguistic co-creators have received the JH Wilkinson Award for digital software and that it has been implemented successfully on the Cori Cray supercomputer XC40. In addition, it is claimed that Julia is able to effectively implement low-level data structures.
Now, I wonder if Julia is (currently) adapted to real-time systems? For example, systems that filter incorrect products in a factory using a computer vision system or integrated systems that decide when to activate an airbag. Would Julia in such a situation be comparable to C? Or are the garbage-free languages the only obvious choice, since garbage can be collected at any time?
