Remove element from array, using slice

Question

I am trying to remove a element from my array using slice, but i can\'t get it to work, look at this piece of code.

    console.log(this.activeEffects); // P         


        

Answer 1

Array.prototype.slice()...

does not alter the original array, but returns a new "one level deep" copy that contains copies of the elements sliced from the original array. Elements of the original array are copied into the new array as follows:

Whereas Array.prototype.splice()...

Changes the content of an array, adding new elements while removing old elements.

This example should illustrate the difference.

// sample array
var list = ["a","b","c","d"];
// slice returns a new array
console.log("copied items: %o", list.slice(2));
// but leaves list itself unchanged
console.log("list: %o", list);
// splice modifies the array and returns a list of the removed items
console.log("removed items: %o", list.splice(2));
// list has changed
console.log("list: %o", list);
