Assume the following Managed Metadata fields:

• Tags (Multiple Taxonomy Field type)
• NewsCategory (Taxonomy Field type)

SP.Taxonomy.TaxonomyField value is represented as SP.Taxonomy.TaxonomyFieldValue object:

//Get Taxonomy Field value
var newsCat = item.get_item('NewsCategory'); 
var newsCatLabel = newsCat.get_label();
var newsCatId = newsCat.get_termGuid();

Multiple SP.Taxonomy.TaxonomyField value is represented as SP.Taxonomy.TaxonomyFieldValueCollection object

//Get Multiple Taxonomy Field value
var newsTags = item.get_item('Tags'); 
for(var i = 0; i < newsTags.get_count(); i++) {
    var newsTag = newsTags.getItemAtIndex(i);
    var newsTagLabel = newsTag.get_label();
    var newsTagId = newsTag.get_termGuid();
