multi splice (or similar) to remove a number of objects in array

January 12, 2023

So i currently have 2 arrays:

const getUniqueRowErrors = [1,3]

const data = [
 {identifier: '000'},
 {identifier: '111'},
 {identifier: '222'},
 {identifier: '3333'},
 {identifier: '444'}
]

The idea is i want to remove the the elements based off the getUniqueRowErrors, so I want the 1st,and 3rd element removed from the the data array, so the end result being:

const data = [
 {identifier: '111'},
 {identifier: '3333'},
 {identifier: '444'}
]

I tried the following but the desired result is incorrect:

const filteredData = getUniqueRowErrors.map((rowToRemove) => data.splice(rowToRemove));

Any ideas how to do the above?

>Solution :

Simply filter by index and check if the index is in the row errors array:

const getUniqueRowErrors = [1,3]

const data = [
 {identifier: '000'},
 {identifier: '111'},
 {identifier: '222'},
 {identifier: '3333'},
 {identifier: '444'}
];

console.log(data.filter((_, i) => !getUniqueRowErrors.includes(i + 1)));
