How to delete multiple items of an array by value with JavaScript?

To delete multiple items of an array by value with JavaScript, we can use the array filter method.

For instance, we write:

const arr = [0, 1, 2, 3, 4];
const removal = 2;
const newArr = arr.filter((itm) => {
  return itm !== removal
});
console.log(newArr)

to call arr.filter to return an array without 2 in it.

To do this, we call filter with a callback that returns itm !== removal.

As a result, newArr is [0, 1, 3, 4].
