Key Categories

| Category | Module | Common Functions | |----------|--------|------------------| | Array | `es-toolkit/array` | `compact`, `head`, `last`, `take`, `drop`, `uniq`, `chunk`, `flatten` | | Object | `es-toolkit/object` | `merge`, `mergeWith`, `clone`, `cloneDeep`, `pick`, `omit` | | String | `es-toolkit/string` | `trim`, `trimStart`, `trimEnd`, `kebabCase`, `camelCase`, `snakeCase` | | Function | `es-toolkit/function` | `debounce`, `throttle`, `memoize`, `once` | | Util | `es-toolkit/util` | `invariant` |

Import Pattern

Always import from specific modules for optimal tree-shaking:

// Good: Import from specific modules
import { compact } from "es-toolkit/array";
import { merge } from "es-toolkit/object";

// Bad: Import from root (larger bundle)
import { compact } from "es-toolkit";
