Thank you. I use undefined very rarely, usually with a hacky looking: "typeof foo === 'undefined'". I'd still rather just type that though than having to setup

Thank you. I use undefined very rarely, usually with a hacky looking: "typeof foo === 'undefined'". I'd still rather just type that though than having to setup up TS. Don't get me wrong, TS is great for the eco-system, for examples it powers the intellisense behind vscode which I use daily. I just do not need to use it directly, so good for me indeed.
