How do I remove one arrays contents from another arrays elements?

Question

I have two arrays as codely illustrated below:

let arrayOne = [1669683600000, 1669770000000, 1669698000000, 1669755600000];
let arrayTwo = [1669683600000, 1669770000000];

I would like to remove the contents of arrayTwo from arrayOne . I thought the code below would work:

let results = arrayOne.filter((item)=> item !== arrayTwo);
console.log('results: ' ,results );

The code above yeilds:

results: [1669683600000, 1669770000000, 1669698000000, 1669755600000]    

The desired results are:

results: [1669698000000, 1669755600000]

How do I achieve my desired results?

Answer 1

Use filter but only include the item if it is not( ! ) in( includes ) arrayTwo

 let arrayOne = [1669683600000, 1669770000000, 1669698000000, 1669755600000]; let arrayTwo = [1669683600000, 1669770000000]; console.log(arrayOne.filter((item)=>.arrayTwo.includes(item)))

Answer 2

Using filter

arrayOne = arrayOne.filter(function(val) {
  return arrayTwo.indexOf(val) == -1;
});
