I am trying to sort the merit list from my array of objects, but on my object, there is a string "Failed", I want to skip it during the sorting but when sorting is done the failed merit should be added at the end
const markSheet = [{ merit: 1 }, { merit: "Failed" }, { merit: 2 }];
const defineMerit = (markSheet) => {
return markSheet
.filter((item) => item.merit !== "Failed")
.sort((a, b) => a.merit - b.merit);
};
console.log(defineMerit(markSheet))example:
[
{
"merit": 1
},
{
"merit": 2
},
{
"merit": "Failed"
}
]
Put the failed check inside the sort callback (compare the difference of whether an item is Failed or not)
const markSheet = [{ merit: 1 }, { merit: "Failed" }, { merit: 2 }];
const defineMerit = (markSheet) => {
return markSheet
.sort((a, b) => (
((a.merit === 'Failed') - (b.merit === 'Failed'))
|| a.merit - b.merit
));
};
console.log(defineMerit(markSheet))or reverse the filter condition afterwards and combine with the sorted array
const markSheet = [{ merit: 1 }, { merit: "Failed" }, { merit: 2 }];
const defineMerit = (markSheet) => {
const sorted = markSheet
.filter((item) => item.merit !== "Failed")
.sort((a, b) => a.merit - b.merit);
return sorted.concat(
markSheet.filter((item) => item.merit === "Failed")
);
};
console.log(defineMerit(markSheet))
