Filter
const array1 = [1, 2, 3, 4, 5]; const array2 = [3, 4, 5, 6, 7]; const difference = array1.filter((element) => !array2.includes(element));
For loop
const array1 = [1, 2, 3, 4, 5]; const array2 = [3, 4, 5, 6, 7]; const difference = []; for (let i = 0; i < array1.length; i++) { if (array2.indexOf(array1[i]) === -1) { difference.push(array1[i]); } }
Set
const array1 = [1, 2, 3, 4, 5]; const array2 = [3, 4, 5, 6, 7]; const set1 = new Set(array1); const set2 = new Set(array2); const difference = [...set1].filter( (element) => !set2.has(element));
Reduce
const array1 = [1, 2, 3, 4, 5]; const array2 = [3, 4, 5, 6, 7]; const difference = array1.reduce((result, element) => { if (array2.indexOf(element) === -1) { result.push(element); } return result; }, []);
