I’m trying to regroup the object values based on keys. The condition to regroup is that
the Key has to be ”APTC/IndianEligibility2" or "APTC/CSR”.
If these keys exit in the eligibilityGroupingMap object, then append their values to the values of the keys “APTC” and “CSR” if these keys exits
else create these keys and push the values.
Delete "APTC/IndianEligibility2" & "APTC/CSR" after pushing their values.
Refer Expected Result
The issue that I’m facing is that I’m getting “Cannot read property 'push' of undefined Javascript”. Tried fixing it by referencing other stack overflow posts. Stuck in it for the last 2 days.
const eligibilityGroupingMap = {
"CHIP": [
"CHILD3",
"CHILD4"
],
"APTC": [
"SELF1"
],
"APTC/IndianEligibility2": [
“SPOUSE2”
],
"Ineligible": [
"CHILD7"
],
"APTC/CSR": [
"CHILD4"
] };
Expected Result:
eligibilityGroupingMap = {
"CHIP": [
"CHILD3",
"CHILD4"
],
"APTC": [
"SELF1”, “SPOUSE2”, “CHILD4"
],
"CSR": [
"CHILD4"
]
"Ineligible": [
"CHILD7"
], };
Code Fiddle
const sortedEligibilityGroupingMap = Object.fromEntries(Object.entries(eligibilityGroupingMap).sort());
const sortedMember = Object.keys(sortedEligibilityGroupingMap).reduce((accValue, currValue) => {
let array = sortedEligibilityGroupingMap[key];
if(key === 'APTC/CSR' || key === 'APTC/IndianEligibility2' || key === 'APTC/IndianEligibility3') {
// eslint-disable-next-line no-prototype-builtins
if('APTC' in sortedEligibilityGroupingMap){
acc['APTC'].push.apply(sortedEligibilityGroupingMap[key]);
} else {
acc.APTC = {};
acc.APTC = sortedEligibilityGroupingMap[key];
}
}
acc[key] = array.sort();
delete acc['APTC/CSR'];
delete acc['APTC/IndianEligibility2'];
delete acc['APTC/IndianEligibility3'];
return acc;
}, {});
console.log('sortedMember'. sortedMember);
const eligibilityGroupingMap = {
CHIP: ["CHILD3", "CHILD4"],
APTC: ["SELF1"],
"APTC/IndianEligibility2": ["SPOUSE2"],
Ineligible: ["CHILD7"],
"APTC/CSR": ["CHILD4"],
};
const sortedEligibilityGroupingMap = Object.fromEntries(
Object.entries(eligibilityGroupingMap).sort()
);
let arrayOfKeyMapping = {
"APTC/CSR": ["APTC", "CSR"],
"APTC/IndianEligibility2": ["APTC"],
};
let groupedObject = {};
Object.entries(sortedEligibilityGroupingMap).map(([key, value]) => {
if (arrayOfKeyMapping[key]) {
let keyList = arrayOfKeyMapping[key];
keyList.map((mkey) => {
if (groupedObject.hasOwnProperty(mkey)) {
groupedObject[mkey].push(...value);
} else {
groupedObject[mkey] = [...value];
}
});
} else {
groupedObject = { ...groupedObject, [key]: value };
}
});
console.log("final Result", groupedObject);Probably the problem is so complex and I have some problem to understand it, but why not do something simpler without using loops? Something like:
const copy = {...eligibilityGroupingMap};
copy.APTC = [
...(eligibilityGroupingMap.APTC || []),
...(eligibilityGroupingMap['APTC/IndianEligibility2'] || []),
...(eligibilityGroupingMap['APTC/CSR'] || [])
];
delete copy['APTC/IndianEligibility2'];
delete copy['APTC/CSR'];
If you prefer to keep your code there are several js error:
accValue and currValue but you're using those params as acc and key, you should use the same name.APTC is key of sortedEligibilityGroupingMap, but you should check in acc (or accValue, depends which name you've decide to use).
