how to compare two arrays and in javascript code example
Example 1: 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]); // false
Example 2: compare arrays javascript
// For regular 1D array
const array1 = [1,2,3,4]
const array2 = [1,2,3,4]
array1.join() === array2.join()
// '1,2,3,4' === '1,2,3,4'
// For anything more complex
const array3 = [1,2,3,[1,2,3]]
const array4 = [1,2,3,[1,2,3]]
JSON.stringify(array3) === JSON.stringify(array4)
