Hi!

I changed from Atom to VS Code, and there is a setting option in Atom which allows one to change the optimization level used in Julia when compiling code. Where do I find this setting in Julia?

I am using Windows

Kind regards

If you go to the extension settings of the Julia extension, you see on top “Additional Args”.  
Edit this in settings.json and change it, that it looks like:

```julia
    ...,
    "julia.additionalArgs": [
        "--optimize=0"
    ],
    ...,

```

Of course without the … lines and with your desired level 0,1,2 or 3.
