> If I'm writing "function getAc..." it's smart enough to complete to "function getActionHandler()", and maybe suggest the correct arguments and a decent jsdoc comment.

I really mean no offense, but your example doesn't sound much different from what old IDEs (say, Netbeans) used to do 15 years ago.

I could design a Swing ui and it would generate the code and if I wanted to override a method it would generate a decent boilerplate boilerplate (a getter, like in your example) along with usual comments and definitely correct parameters list (with correct types).

Is this "AI Code" thing something that appears new because at some point we abandoned IDEs with very strong intellisense (etc) ?
