If I want to throw an exception if an object is null or undefined, Co-pilot will do the if and the exception throw using the right error class, and a more meaningful error message that what I usually came up with.
If want to map some random technical data table to something useful in my programming language, I can copy paste the data from the documentation in pdf or html into a comment block, give an example, and co-pilot will write everything in the format I want.
If I want to slightly refactor some code, I can do it once or twice and co-pilot can help me a lot to refactor the remaining.
If I want to have a quick http server in nodejs, I don't have to Google anything.
It's a lot of tiny things like this.
