Here is the code snippet:
$scope.items.map(function (item) {
if(item.keywords.indexOf($scope.formData.keyword) != -1){
array.push(bono);
}
})
I am trying to figure out how to execute a function with all the elements of the array once the map function finishes. Any ideas on how I can achieve this? I considered stacking the calls, but I'm not sure how to implement it.
Appreciate any help. Thank you.
Once $scope.items is confirmed to be an array, as noted in the question, you can proceed knowing that Array.prototype.map() operates synchronously. This means that you can place the next statement directly after this code, and it will run once the .map() has finished processing.
One way to handle multiple promises at once is by utilizing the Promise.all() method:
var asyncTasks = [task1, task2, taskN].map(function(task){
return storage.fetch('data').then(function(response){
return response;
})
})
Promise.all(asyncTasks).then(function(response) {
console.log("All results combined", response);
})
Give this a shot:
var list = [];
$scope.items.forEach(function (item) {
if(item.tags.includes($scope.formData.tag)){
list.push(item);
}
});
customAction(list);

Here's a suggestion
$scope.items.filter(function (item) {
if(item.tags.includes($scope.formData.tag)){
result.push(answer);
}
}).finally(function(){}).then(function(){});
