I have an object that contains objects. How do i filter out the value of "title" based on whether the id is matching?
{
"0": {
"id": 1912,
"title": "Fiction",
},
"1": {
"id": 1957,
"title": "Non-Fiction",
},
"2": {
"id": 1958,
"title": "Literature",
},
}
For example, if the const id=1958, then the output: Literature
Output:
Literature
You can try this:
let data = {
"0": {
"id": 1912,
"title": "Fiction",
},
"1": {
"id": 1957,
"title": "Non-Fiction",
},
"2": {
"id": 1958,
"title": "Literature",
},
};
let getTitle = (obj, id)=>{
return Object.values(obj).filter(x=>x.id===id)?.[0]?.title
};
console.log(getTitle(data,1958))You can also use find instead of filter.
Without optional chaining as per OPs comment:
let data = {
"0": {
"id": 1912,
"title": "Fiction",
},
"1": {
"id": 1957,
"title": "Non-Fiction",
},
"2": {
"id": 1958,
"title": "Literature",
},
};
let getTitle = (obj, id)=>{
let element = Object.values(obj).find(x=>x.id===id);
return element ? element.title : "";
};
console.log(getTitle(data,1958))
