🔥 TypeScript Tip #10 🔥 Using a crazy trick I picked up from @AndaristRake, you can throw detailed error messages for type checks. Here, I move a runtime check in a function to the type level, meaning you get a detailed error if you use it wrong.

🔥 TypeScript Tip #12 🔥 Ever wanted just a _bit_ of autocomplete? Here, we create a TypeScript helped called LooseAutocomplete which gives us autocomplete while also allowing arbitrary values. Picked up this tip from @GavinRayDev - worth a follow!
