Pattern matching with infer isn’t just for Promises and Objects. You can deconstruct Tuples and Arrays element by element in Type Space, mirroring the exact syntax of JavaScript’s array destructuring and spread operators.
An exhaustive guide to typing collections in TypeScript. Learn the syntax differences between T[] and Array, union array typing precedence, labeled tuple elements, rest tuples, and why readonly arrays prevent array mutation bugs.
In Go, an Array has a fixed length determined at compile time. A Slice is a lightweight, dynamically sized view into an underlying array. Understanding slice capacity (cap) prevents accidental memory reallocation overhead.
