Type Utilities

Description

The type utilities module provides functions for checking and identifying JavaScript value types, including enhanced type detection for arrays, elements, and null values.

typeOf

Returns the type of a value as a string, with enhanced detection for arrays, DOM elements, and null.

import { typeOf } from '../src/utils/type.js';

typeOf('hello'); // "string"
typeOf(42); // "number"
typeOf([1, 2, 3]); // "array"
typeOf(null); // "null"
typeOf(document.body); // "element" (in browser)

isType

Checks if a value is of a specific type.

import { isType } from '../src/utils/type.js';

isType('hello', 'string'); // true
isType([1, 2], 'array'); // true
isType(null, 'null'); // true
isType(42, 'string'); // false
