quesk

library2.0.1jsnpmunverified

Quesk is a lightweight JavaScript library (v2.0.1, last updated 2017) providing abstract data types for both Queue and Stack collections. It supports both CommonJS and ES module imports, and includes a UMD bundle for browser use. The API is minimal, offering methods like append, prepend, shift, pop, first, last, and length. It differentiates from libraries like `denque` or `double-ended-queue` by focusing solely on basic first-in-first-out and last-in-first-out operations without additional features, making it suitable for small projects or educational use. However, it has no active maintenance and may lack modern JavaScript optimizations.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

queuesk (default export)

✓ import quesk from 'quesk'

✗ const quesk = require('quesk')

ESM usage requires Node >= 4 or a bundler. Default export is a function.

Queuesk as CommonJS require

✓ const quesk = require('quesk').default || require('quesk')

✗ const quesk = require('quesk'); quesk()

CJS users may need .default if the module uses ESM interop. Check your Node version.

Browser global

✓ <script src="https://unpkg.com/quesk/dist/quesk.min.js"></script>

✗ window.quesk()

UMD exposes the library as window.quesk (function).

Shows how to create Queue and Stack instances, add items, access first/last, and remove items.

import quesk from 'quesk'; // Queue example const queue = quesk(); queue.append('a'); queue.append('b'); console.log(queue.first()); // 'a' queue.shift(); console.log(queue.length()); // 1 // Stack example const stack = quesk(); stack.prepend('x'); stack.prepend('y'); console.log(stack.last()); // 'y' stack.pop(); console.log(stack.length()); // 1

Debug

Known issues

breakingBreaking change: In v2, the default import is a function that returns an object, not the object itself.

fix

Always call quesk() to get an instance.

affects: >=2.0.0

gotchaThe library mutates the internal array; there is no immutability support.

fix

Create a new instance if you need to preserve state.

affects: *

deprecatedNo new releases since 2017; project is abandoned.

fix

Consider using actively maintained alternatives like denque or double-ended-queue.

affects: *

gotchaMethod names (append, prepend, shift, pop) mimic array methods but do not behave exactly like Array.prototype methods (e.g., shift returns undefined, not the removed element).

fix

Use first()/last() to access elements before removing; pop()/shift() only remove and return the element.

affects: *

Errors

Common errors & fixes

TypeError: quesk is not a function

Using default import incorrectly; missing parentheses or using wrong import style.

fix

Ensure you call quesk() after import: const q = quesk();

Cannot find module 'quesk'

Package not installed or not found in node_modules.

fix

Run 'npm install quesk' or 'yarn add quesk'

Object(...) is not a function

Transpilation issues with Karma or Jest; missing babel transform for es modules.

fix

Add 'transform-es2015-modules-commonjs' to your Babel configuration.
