Knockout js Array First

arrayFirst

Array firstly returns only first items which are matched.

For Example

  var findSelectedCodeSetFromLabel = function (label, codeSet) {

         try {

                 if (codeSet != null && codeSet.length > 0) {

                     return ko.utils.arrayFirst(codeSet, function (item) {

                         return (item.Label.toLowerCase().indexOf(label.toLowerCase()) > -1);

                     });

                 };

          }

          catch (ex) {

               logExceptions(ex);

          }

  };
