check if 2 arrays are equal javascript
const a = [1, 2, 3]; const b = [4, 5, 6]; const c = [1, 2, 3]; function arrayEquals(a, b) { return Array.isArray(a) && Array.isArray(b) && a.length === b.length && a.every((val, index) => val === b[index]); } arrayEquals(a, b); // false arrayEquals(a, c); // true
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
javascript get elements that exist in two arrays
function getArraysIntersection(a1,a2){ return a1.filter(function(n) { return a2.indexOf(n) !== -1;}); } var colors1 = ["red","blue","green"]; var colors2 = ["red","yellow","blue"]; var intersectingColors=getArraysIntersection(colors1, colors2); //["red", "blue"]
check if 2 arrays are equal javascript
var arraysMatch = function (arr1, arr2) { // Check if the arrays are the same length if (arr1.length !== arr2.length) return false; // Check if all items exist and are in the same order for (var i = 0; i < arr1.length; i++) { if (arr1[i] !== arr2[i]) return false; } // Otherwise, return true return true; };
