` . Restarting Julia is for example useful if you redefined a struct or a typed global variable.

I added it to the startup.jl file and tested it in VS Code and in a standalone Julia REPL and it seems to work very well. For the latter, it restarts the REPL in the same window very quickly in Julia 1.9 and thus, it might be seen as a “clear workspace” analogue.

What is the `--project` for?

A Project is a folder that contains a `Project.toml` file. This file contains a list of the packages that you are using for this project. This avoids problems in the long run. For details see: [Working with Julia projects | Julia programming notes](https://ufechner7.github.io/2022/08/16/julia-projects.html)
Starting Julia without `--project` will use the global Project.toml . To see see what is in your global environment type `]st` . Try to keep your global environment clean.

If you’re using VSCode you can use ALT + J + K to kill/close Julia, then you can use ALT + J + O to open a new Julia REPL. I tend to hold down the ALT key then type “jkjo” to perform this quickly.
This will not impact any packages installed, but you will have to reload packages in like “using Package”.

You can also use `Ctrl` + `Shift` + `P` and then enter `restart` and select `Julia: Restart REPL` in VSCode.
If you do not use any other command with `restart`, it will be at the top position after entering `restart` and you can directly execute it with `enter`.
If you haven’t entered a different command, you can even skip entering `restart` and hit `enter` directly.
This works if you do not have an open REPL, too.

You can simply type `ALT` + `j` and then `ALT` + `r` to close the running Julia session, if any, and then (re)start a new one. The `r` is mnemonic for “restart”.

You can restart Julia by simply closing the Julia REPL (or the terminal/IDE you’re using) and reopening it. If you’re using VS Code, there’s a “Restart Julia” option in the Julia extension toolbar.
Restarting Julia won’t affect your installed packages; they remain intact. However, you’ll need to reload any packages manually using PackageName after restarting.
