This is a "let 'im cook" instance. Reading through the article, the author makes the argument for the philosophy of progressive disclosure. The last paragraph brings it together and it's a reasonable take: > When you’ve typed text, the program is valid. When you’ve typed text.split(" "), the program is valid. When you’ve typed text.split(" ").map(word => word.length), the program is valid. Since the program is valid as you build it up, your editor is able to help you out. If you had a REPL, you could even see the result as you type your program out. In the age of CoPilot and agent coders I'm not so sure how important the ergonomics still are, though I dare say coding an LSP would certainly make one happy with the argument.
