I have this code
$scope.items.map(function (item) {
if(item.keywords.indexOf($scope.formData.keyword) != -1){
array.push(bono);
}
})
And I need to execute a function with all the elements of the array when the map finish. How can I do this? I thought to stack the calls but I don't know how to do it.
Thanks

The map() method returns the new array after processing each element for the given array. It accepts a callback function, which has currentItem as a mandatory parameter.
To use a map() inside a map() function in React: Call map() on the outer array, passing it a function. On each iteration, call the map() method on the other array.
How do you break a map in react JS? If you want to map() through the last N elements of an array in React, pass a negative index to the Array.To break a map() loop in React: Call the slice() method on the array to get a portion of the array. Call the map() method on the portion of the array.
map function? Not possible, We can't break #array. map, it will run for each element of array. To solve your problem, you can use slice first then map, slice first 5 elements of array then run map on that.
As soon as $scope.items is an array as you stated in the question and the Array.prototype.map() is synchronous - which means that you simply put the next statement after this code and it will be executed after the .map() has completed processing.
