🔥 TypeScript Tip #5 🔥 The 'extends' keyword is very powerful in TypeScript. Here, I use it to narrow the value of a generic to enable some beautiful autocomplete/inference.
TypeScript tip: use `as const` after literals to: ‣ Recursively set object properties to readonly ‣ Make arrays readonly tuples ‣ Disable type widening

Here's two TypeScript tips rolled into one: 1. TypeScript magic is everywhere, even in Node's built-in types 2. I bet you didn't know this was legal TS: error: [message: string]
Stop memorizing TypeScript utility types. Here's the clean cheat sheet you'll need! 🔥 Bookmark this!👇

You’re writing extra code if you’re not using this TypeScript trick!
If you're using Tailwind, don't sleep on child selectors. They clean up your styles and eliminate repetition. Vibe coding agents aren't smart enough to do this. (if you're using CSS, keep scrolling)
using keyof/typeof is my favorite way to keep TypeScript types in sync with options:
In tech, everything is a wrapper: • Next.js is a wrapper over React • React is a wrapper over JavaScript • JavaScript is a wrapper over C++ • C++ is a wrapper over Assembly • Assembly is a wrapper over 1s and 0s
TypeScript tip: stop using optional properties so much in your internal app logic. ❌ prop?: string; ✅ prop: string | undefined; Being explicit about undefined values eliminates the silent bugs that happen when you forget to provide a value.
TypeScript tip: Avoid making a property optional when the property isn’t valid in a certain case. Instead, declare 2 separate types, and use Omit to avoid copy/paste. Example: Many objects lack an id until they're saved. So declare a separate "Unsaved" type. #typescript
Quick JavaScript Tip: If you're writing JavaScript in @code, add `// @ts-check` to the top of your file to gain some benefits of TypeScript checking #vscode #javascript #typescript #programming
Few handy built-in TypeScript types: 🔸 Partial - makes all props of the type parameter optional 🔸 Omit - omits the specified properties in the second type parameter from the first one 🔸 Parameters - gets the parameter types of a function

Watch out! TypeScript 4.4 changes the default type for errors caught in catch clauses from `any` to `unkown`. This means that you can no longer access properties such as `message` without asserting a type first (i.e. `(error as Error)`. #TypeScriptTricks #TypeScript #DEVCommunity
