Installing Julia#

If you haven’t already done so, visit the Julia install page and download juliaup for your platform.

Once juliaup is installed, install a julia version using juliaup add release (or use a different version like lts instead of release).

Run Julia#

Check that when you execute julia the REPL starts, like this:
