Worked through Algorithms in Go: Determine if a number is in a list
Passed the tests without needing to find the solution, so that's a win.
Had to remember to grab the second value from the range operator like for _, i := range items instead of using foreach($i in $items) like PowerShell would do. It's more similar to using hashtables with GetEnumerator().
Used codespaces with Docker and also experimented with WSL2 and Visual Studio Code mounting the directory from inside WSL2.
