 #### AbortController Example
 
 The following code snippet shows how to upload a file using S3's putObject API in the browser with support to abort the upload. First, create a controller using the `AbortController()` constructor, then grab a reference to its associated AbortSignal object using the AbortController.signal property. When the `PutObjectCommand` is called with `.send()` operation, pass in AbortController.signal as abortSignal in the httpOptions parameter. This will allow you to abort the PutObject operation by calling `abortController.abort()`.
