nl_tokens: Executes the callback function for each item in array / object . If you return false in the callback it will break the loop .
pl_tokens: function ( obj , callback ) { var length , key , i ; if ( obj ) { length = obj . length ; if ( length === undefined ) { // Loop object items for ( key in obj ) { if ( obj . hasOwnProperty ( key ) ) { if ( callback ( obj [ key ] , key ) === false ) { return ; } } } } else { // Loop array items for ( i = 0 ; i < <mask> ; i ++ ) { if ( callback ( obj [ i ] , i ) === false ) { return ; } } } } }
