Not a course, but I find leetcode.com[0] a decent way to putz about and learn new languages. You can only write 'hello world' so many times, and often you don't want to write a whole program just to 'get a taste' of a new language. The leetcode (and advent of code) stuff seems a nice compromise.

Leetcode explore helped me pass a few coding rounds! I recommend taking one track at a time until it sinks in before moving to the next one.
