📖 Usage

Basic Usage

import { typeOf } from '@se-oss/typeof';

typeOf(undefined); // 'undefined'
typeOf(null); // 'null'
typeOf(true); // 'boolean'
typeOf('hello'); // 'string'
typeOf(123); // 'number'
typeOf([]); // 'array'
typeOf({}); // 'object'
typeOf(new Date()); // 'date'
typeOf(/abc/); // 'regexp'

TypeScript Support

The library provides a TypeOf<T> conditional type that maps TypeScript types to their runtime string representations.

import type { TypeOf } from '@se-oss/typeof';

type MyType = TypeOf<string>; // 'string'
type MyDate = TypeOf<Date>; // 'date'

The typeOf function also utilizes this type for better return type inference:

const result = typeOf('hello'); // Inferred as 'string'
