console.log(keyword[1]);

you cant access with keyword.1 but as array do keyword[1]

in another scenario


for(var i=0;i< items.length;i++) { 
for(var j=0;j< itemfield.length;j++) {
    var field=itemfield[j].name
    if (items.hasOwnProperty(field)) {  
       console.log(items[i][field]);
    }
}
}

use array had object than use , it is like multidimensional array
items[i][field]
where items[i] have object it property can be access as like we do with array .
