Hello,
I’m new to Julia and trying to tackle learning arrays. I’m using Julia 1.6 and trying to use double semicolons to horizontally concatenate numbers into an array, following the tutorial example shown below:
As you can see, I’m getting a 4-element vector instead of the expected 1x4 matrix shown in the tutorial. I even copied and pasted the tutorial to make sure I wasn’t mistyping.
Please help me to see what I am missing.

That feature was added in 1.7

Thank you!
The website url had v1 and I didn’t see a version 2 so I thought it wasn’t a version issue.
