I am currently student and intelliJ tells me I have to simplify this if-statement but I have no idea how. Maybe somebody can help me.
The simplification is probably that, if condition
is a boolean, :
if (condition) {
return true;
}
else {
return false;
}
is equivalent to
return condition;
However there also seems to be a logical error in your test.
$scope.relrechtsform.indexOf(dataService.dic.alt.rechtsformKanlei ||
dataService.dic.neu.rechtsformKanlei ) !== -1
Does not mean the same thing as :
$scope.relrechtsform.indexOf(dataService.dic.alt.rechtsformKanlei) !== -1 ||
$scope.relrechtsform.indexOf(dataService.dic.neu.rechtsformKanlei) !== -1
Maybe you're looking for this:
$scope.vergleich = function () {
return $scope.relrechtsform.indexOf(dataService.dic.alt.rechtsformKanlei || dataService.dic.neu.rechtsformKanlei ) !== -1;
};
Tân's version is a correct answer to your question. However, with recent JavaScript you can simplify even more thanks to array.includes
:
$scope.vergleich = () =>
$scope.relrechtsform.includes(dataService.dic.alt.rechtsformKanlei || dataService.dic.neu.rechtsformKanlei)
You can just use your condition instead of using IF else
statement -:
$scope.vergleich = function () {
return ($scope.relrechtsform.indexOf(dataService.dic.alt.rechtsformKanlei ||
dataService.dic.neu.rechtsformKanlei ) !== -1);
};
