const dataSet = [{
categoryId: 100,
parentCategoryId: -1,
name: "Business",
keyword: "Money",
},
{
categoryId: 200,
parentCategoryId: -1,
name: "Tutoring",
keyword: "Teaching",

function solution(X) {
// search your keyword
dataSet.map((item)=>{
console.log("Item List: ", item);
if (X === item.categoryId){
const displayData = `\n\t ParentCategoryId : ${item.parentCategoryId} \n\t Name : ${item.name} \n\t Kewords : ${item.keyword}`;

Answer 1

Below method will solve your problem.
function solution(cId){
let result = null;
const getParentNode = function(parentId){
const parentNode = dataSet.find(elm => elm.categoryId === parentId);
if(parentNode && parentNode.keyword === ""){
return getParentNode(parentNode.parentCategoryId);
}
return parentNode;
}
for(let i=0; i<dataSet.length; i++){
if(dataSet[i].categoryId === cId){
if(dataSet[i].keyword === "")
result = {...dataSet[i], keyword: getParentNode(dataSet[i].parentCategoryId).keyword};
else
result = dataSet[i];
break;
}
}
return result;
}

This may probably help you!
var result = result1.filter(function (o1) {
return result2.some(function (o2) {
return o1.id === o2.id; // return the ones with equal id
});
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));
