How can you compare arrays of objects with arrays using JavaScript?
I am looking to evaluate an array of objects based on specific conditions.
If the
targetvalueis the same and thecodevalue is not present in thearraylist, return the array of objects.Otherwise, if the
targetvalueis the same and thecodehas the same value in thearraylist, return the array of objects.
Otherwise, return an empty array []
var arraylist =["IT","FI"];
var arrobj1 =[
{id:1, name: "sonu", code: "IT", targetvalue: "908"},
{id:2, name: "abi", code: "IT", targetvalue: "834"},
{id:3, name: "lisa", code: "SP", targetvalue: "834"},
{id:4, name: "ben", code: "FI", targetvalue: "234"},
]
Expected Output
//same value, and includes `IT`
[]

var arrobj2 =[
{id:1, name: "sonu", code: "IT", targetvalue: "908"},
{id:2, name: "abi", code: "IT", targetvalue: "834"},
{id:3, name: "lisa", code: "SG", targetvalue: "234"},
{id:4, name: "ben", code: "SP", targetvalue: "234"},
]
Expected Output
//same targetvalue and not included `FI or IT`, so return
[
{id:3, name: "lisa", code: "SG", targetvalue: "234"},
{id:4, name: "ben", code: "SP", targetvalue: "234"},
]

var arrobj3 =[
{id:1, name: "sonu", code: "IT", targetvalue: "908"},
{id:3, name: "lisa", code: "FI", targetvalue: "234"},
{id:4, name: "ben", code: "FI", targetvalue: "234"},
]
Expected Output
// targetvalue and code are the same
[ {id:3, name: "lisa", code: "FI", targetvalue: "234"},
{id:4, name: "ben", code: "FI", targetvalue: "234"}]
I have attempted to use the following code for this comparison:
const checkIdList = list => {
const idlist = ['IN', 'FI'];
const resultarray = list
.map((obj, i) => list.find((elem, index) => {
if (i !== index && elem.targetvalue === obj.targetvalue &&
(element.code === obj.code || idlist.includes(element.code))) {
return obj;
}
}))
.filter(x => x);
return resultarray;
};
var finalResult = this.checkIdList(arrobj1);
