javascript Compare two arrays regardless of order
const isEqual = (a, b) => JSON.stringify(a) === JSON.stringify(b);
// Examples
isEqual([1, 2, 3], [1, 2, 3]); // true
isEqual([1, 2, 3], [1, '2', 3]); // falsejavascript Compare two arrays regardless of order
const isEqual = (a, b) => JSON.stringify(a) === JSON.stringify(b);
// Examples
isEqual([1, 2, 3], [1, 2, 3]); // true
isEqual([1, 2, 3], [1, '2', 3]); // falsebest way compare arrays javascript
// To compare arrays (or any other object):
// Simple Array Example:
const array1 = ['potato', 'banana', 'soup']
const array2 = ['potato', 'orange', 'soup']
array1 === array2;
// Returns false due to referential equality
JSON.stringify(array1) === JSON.stringify(array2);
// Returns true
// Another Example:
const deepArray1 = [{test: 'dummy'}, [['woo', 'ya'], 'weird']]
const deepArray2 = [{test: 'dummy'}, [['woo', 'ya'], 'weird']]
deepArray1 === deepArray2;
// Returns false due to referential equality
JSON.stringify(deepArray1) === JSON.stringify(deepArray2);
// Returns truecomparing two arrays in javascript
const arr1 = [1, 2, 3];
const arr2 = [1, 3, 3];
if (arr1.length !== arr2.length) return console.log("false");
for (let i = 0; i < arr1.length; i++) {
for (let j = 0; j < arr2.length; j++) {
if (arr1[i] === arr2[j]) {
console.log("yes match", arr1[i], arr2[j]);
continue;
}
console.log("no match", arr1[i], arr2[j]);
}
