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); // truejavascript 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"]Copyright © 2021 Codeinu
