Code

Verified usage

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

Queue

✓ import Queue from 'ss-queue'

✗ import { Queue } from 'ss-queue'

Default export; named import will not work.

Queue

✓ const Queue = require('ss-queue')

✗ const { Queue } = require('ss-queue')

CommonJS require returns the default export directly, not an object with Queue property.

QueueType

✓ import type { IQueue } from 'ss-queue'

TypeScript type for the Queue interface; exported as IQueue.

Creates a queue, enqueues two elements, dequeues one, checks size and emptiness, then clears the queue.

import Queue from 'ss-queue'; const queue = new Queue<number>(); queue.enqueue(1); queue.enqueue(2); console.log(queue.dequeue()); // 1 console.log(queue.size()); // 1 console.log(queue.isEmpty()); // false queue.clear(); console.log(queue.isEmpty()); // true

Debug

Known issues

gotchaQueue.dequeue() returns undefined if queue is empty (not throwing an error). Make sure to check isEmpty() before calling dequeue.

fix

Always check queue.isEmpty() before dequeue or use optional chaining.

affects: >=1.0.0

Errors

Common errors & fixes

TypeError: Queue is not a constructor

Using named import instead of default import.

fix

Use `import Queue from 'ss-queue'` (default import) instead of `import { Queue } from 'ss-queue'`.
