How can i get only single column data from dynamo db by calling lambda function in java script?

By using ProjectionExpression we can get single column.
eg:
{
"TableName" : "your table name",
"ProjectionExpression" : "column name"
}
you can use this. http://docs.aws.amazon.com/amazondynamodb/latest/gettingstartedguide/GettingStarted.NodeJs.04.html
