# Amazon SQS Examples
<a name="sqs-examples"></a>

Amazon Simple Queue Service (Amazon SQS) is a fast, reliable, scalable, fully managed message queuing service. Amazon SQS lets you decouple the components of a cloud application. Amazon SQS includes standard queues with high throughput and at-least-once processing, and FIFO queues that provide FIFO (first-in, first-out) delivery and exactly-once processing.

The JavaScript API for Amazon SQS is exposed through the `AWS.SQS` client class. For more information about using the Amazon SQS client class, see [https://docs.amazonaws.cn/AWSJavaScriptSDK/latest/AWS/SQS.html](https://docs.amazonaws.cn/AWSJavaScriptSDK/latest/AWS/SQS.html) in the API reference.
