$.isArray(value)

Type guard that returns true when the value is an array.

Importing this module attaches isArray to the $ factory as a static helper, mirroring jQuery’s $.isArray. It is a thin wrapper around the native Array.isArray, so it returns true for genuine arrays (including arrays from other realms) and false for array-like values such as NodeList or arguments.

Signatures

$.isArray(value: unknown): value is unknown[];

Parameters

• value (unknown) — the value to test.

Returns

true if value is an array, otherwise false.

Examples

import $ from "dabbyjs";
import "dabbyjs/utils/isarray/isarray";

$.isArray([1, 2, 3]);                 // true
$.isArray(document.body.children);    // false (HTMLCollection)
$.isArray("dabby");                   // false

Notes

Included in the full build. For new code, prefer the native Array.isArray directly — this helper exists for jQuery API compatibility.
