nl_tokens: Iterate each element of an object
pl_tokens: function each ( obj , callback , <mask> ) { if ( ! obj ) { return ; } var key ; // Is Array? // Array.isArray won't work, not only arrays can be iterated by index https://github.com/flowjs/ng-flow/issues/236# if ( typeof ( obj . length ) !== 'undefined' ) { for ( key = 0 ; key < obj . length ; key ++ ) { if ( callback . call ( context , obj [ key ] , key ) === false ) { return ; } } } else { for ( key in obj ) { if ( obj . hasOwnProperty ( key ) && callback . call ( context , obj [ key ] , key ) === false ) { return ; } } } }
