One thing to keep in mind is that using the name 'newWeek' for both a function parameter and a local variable can lead to confusion. In this scenario, when you assign an object to this variable and compare each element of weekList with it, the comparison will fail due to object references. The newly created object is only referenced by the variable newWeek.
To address this issue, consider renaming either the local variable to newWeekObject or the function parameter to
newWeekName</code. I would suggest renaming the function parameter since the local variable is not necessary here.</p>
<p>In addition, the current approach of looping through <code>$scope.weekList
and comparing each element's name with
newWeekName</code seems flawed. At every step, you are either showing an alert or adding a new element to the array, which causes the array's length to increase and results in an infinite loop.</p>
<p>A better approach would be to use the <code>Array#some
method to check if the target week exists before deciding whether to insert a new week into the list. Here is an example:
$scope.addWeek = function(type, newWeekName, index) {
var weekExists = $scope.weekList.some(function(week) {
return week.weekName === newWeekName;
});
if (weekExists) {
alert("The week already exists.");
}
else {
$scope.weekList.unshift({
weekName: newWeekName,
modifiedTime: $filter('date')(new Date(), "h:mm a MMM d, yyyy")
});
}
$("#" + type + "weekmodalpopup").modal('toggle');
};
In this code snippet, unshift is used instead of
splice(0, 0)</code for simplicity. If you wish to insert a new week at a specific index, you can replace it with <code>$scope.weekList.splice(index, 0, { ... }
