Tests:

  • Lodash : small base

     
    const notInArr1 = _.difference(arr2, arr1)
    ​

  • Set & Filter: small base

     
    const notInArr1 = arr2.filter(value => !arr1.includes(value));
    ​

  • Set & Filter: large base

     
    const notInArr2 = arr1.filter(value => !arr2.includes(value));

  • Lodash: large base

     
    const notInArr2 = _.difference(arr1, arr2)
