you can create own find function, important part break loop when match element.

var data = [{id: 1, name: 'a'}, {id: 2, name: 'b'}];    function altfind(arr, callback) {    (var = 0; < arr.length; i++) {      var match = callback(arr[i]);      if (match) {        return arr[i];        break;      }    }  }    var result = altfind(data, function(e) {    return e.id == 2;  })    console.log(result)
