Is there a more concise and elegant way to check if ['pk'] exists in the first item of an array before executing certain tasks? The array may not always have data, leading to bloated code.
I'm looking for a streamlined solution in Javascript that avoids console errors when the array is empty. Any suggestions?
var $selectedItem = $scope.selectedItem[0] || null;
if($selectedItem && $selectedItem['pk']) { ... }
Without further verification of the initial part of the boolean and statement being false, a more succinct approach is:
if ($selectedItem && $selectedItem['pk']) {
...
}
In my opinion, you could streamline the code by doing the assignment within the conditional check:
if ($selectedItem && ($selectedPk = $selectedItem['pk'])) {
...
}
It seems like there is potential to merge both into one.
let selected = $scope.selectedItem[0] || null;
if(selected) {
let selectedPK = selected['pk'];
if(selectedPK) {
...
}
}
And here's another one for you ;)....
if ($scope.selectedItem[0] && $scope.selectedItem[0].pk !== undefined) {
// perform actions
}
