why this kind of bad design is made on js? Is there any special reason to design the automatic semicolon insertion like this?
Why does this code work? Are commas in match statements just a convention?Let's take a look what the Rust reference says about this:
I'm attempting to write a deployment script that checks the OS major version, then runs command based on that. I can grab that just fine with [System.Environment]::OSVersion.Version.Major, but when I attempt to use that in an if/elseif statement, I always get the first condition, and somehow the variable changes.
I've been using PowerShell for a number of years, and I thought I had a handle on some of its more 'eccentric' behaviour, but I've hit an issue I can't make head nor tail of...
