How to check the equality of two arrays with the same object properties but different sequence

Question

I want to compare two Arrays of object and check the equality with the same properties but different sequences, for example

const array1 = [{id:1,name:'john'},{id:2,name:'wick'}]; const array2 = [{id:2,name:'wick'},{id:1,name:'john'}]; // How can I check if these arrays have the same objects

These two answers are for non object data, I need to work with object data — Usama Abdul Razzaq

const array1 = [{ id: 1, name: 'john' }, { id: 2, name: 'wick' }]; const array2 = [{ id: 2, name: 'wick' }, { id: 1, name: 'john' }]; const array3 = [{ id: 2, name: 'abc' }, { id: 1, name: 'john' }]; console.log('array1 matches array2? ', isMatched(array1, array2)); console.log('array3 matches array2? ',isMatched(array3, array2)); function isMatched(arr1, arr2) { //sort arrays arr1.sort((a, b) => a.id - b.id); arr2.sort((a, b) => a.id - b.id); return arr1.every((obj, i) => Object.keys(obj).length === Object.keys(arr2[i]).length && Object.keys(obj).every(prop => obj[prop] === arr2[i][prop]) ) }

a & b refer to array elements (elements here are objects so, I try to sort them according to id property) .. same as sorting array of numbers arr.sort((a, b)=> a-b)
