JavaScript Typed_arrays Guide

TypedArrays provide binary data access with specific numeric types: Int8, Uint8, Float32, etc. for performance-critical code. The guide walks through TypedArray Types. Int8Array, Uint8Array, Uint8ClampedArray, Int16Array, Uint16Array, Int32Array, Uint32Array, Float32Array, Float64Array, BigInt64Array, BigUint64Array. Size: `new Int32Array(10)` — 10 elements × 4 bytes = 40 bytes. Fill: `.fill(0)`. Methods: `.slice()`, `.subarray()`, `.set()`, `.map()`, `.filter()`, `.reduce()`, `ArrayBuffer` backing storage. The guide is organized into 1 sections that build on each other, each pairing a prose explanation with runnable code. Related guides: Arrays, Strings, Numbers, Math, Date. This is one of 145 JavaScript guides on JS Reference — see the full list on the guides page.
