unknown type is unknown. So, if you want to use correctly, you should do type narrowing. Then, you can use is-kit. github.com/nyaomaru/is-kit

TypeScript: JSON.parse gives you unknown. Don’t trust it. → prove it first

Really appreciate the feature again 🙏 Handling `unknown` in TypeScript keeps coming up. Type safety should feel like part of your code — not something separate.

Typescript unknown is the universe.

unknown type is unknown. So, if you want to use correctly, you should do type narrowing. import { isString, isNull, or } from 'is-kit'; const input: unknown; const isNullableString = or(isString, isNull); if (isNullableString(input)) { input; // string | null 😸 }

The life of Gen Z : - College degree is worthless - Rent is half your paycheck - Al is replacing your job - Houses cost 30x your salary - Boomers asking why you're stressed

Handling `unknown` in TypeScript is painful. Most tools separate validation from your code. I wanted something that just extends your existing `if` statements. dev.to/nyaomaru/handl…

Honored to be featured again 🙏 After comparing Zod vs is-kit, I realized they’re not competitors. They solve different problems. → dev.to/nyaomaru/is-ki…

Is a function an object in TypeScript? Yes.

This is not a library comparison. It’s a design question: 👉 Where do you enforce type safety? - Zod → at the boundary - is-kit → inside control flow Same problem, different layer. Read more 👇 dev.to/nyaomaru/is-ki…

Honored to be featured in TypeScript Trends 🙏 I’ve been exploring a slightly different approach to validation: - Zod → schema-first - is-kit → composable type guards Not better/worse, just different trade-offs. github.com/nyaomaru/is-kit

Zod feels great at boundaries. But inside your app? - if (isUser(x)) - arr.filter(isUser) Type guards fit the control flow better. 👉 schema vs guard is a design choice, not a tool choice Full comparison 👇 dev.to/nyaomaru/is-ki…

Zod vs is-kit — same goal, different philosophy. - Zod → schema → type - is-kit → guard → control flow narrowing Not “which is better?” 👉 Where do you enforce type safety in your design? Built a comparison 👇 dev.to/nyaomaru/is-ki…

{} is NOT an empty object. It means: "any value except null and undefined" Yes, even strings and numbers.

TypeScript type system: primitives → objects → unions → unknown A carefully built structure. Add "any" at the top, and type safety disappears instantly.

Collision detection feels unfair sometimes, right? That’s because SVG uses its viewBox, not the actual shape. It breaks collision. 👇 how I fixed it dev.to/nyaomaru/build…
