Check if bucket exists

Basic workflow
1. Create a BosClient instance.
2. Run the doesBucketExist() method.

Example code

                JavaScript
                
            

                client.doesBucketExist(<BucketName>)             //Specify the bucket name
  .then(function(response) {
      if(response) {
          console.log('Bucket exists');
      }
      else {
          console.log('Bucket not exists');
      }
  })
  .catch(function() {
 // Query failed, add your own code to handle the exception
  });
