remove At

Remove an element from an array at some position.


The size of the array shrinks by one. The element is removed from the array at the position you want. All the other elements after it are moved (shifted) to down to the next lower position. So, an array that has the numbers 4, 5, 9, 3, 2 will be 4, 5, 3, 2 if 9 is removed from the array at index 2. It looks like this in blocks:

let myNumbers = [4, 5, 9, 3, 2];
let item = myNumbers.removeAt(2);


  • index: the position in the array to get the element from.


  • the element in the array from the position you chose.


Remove the most dangerous level of radiation from the list.

let radLevels = ["alpha", "beta", "gamma"];
let level = radLevels.indexOf("gamma");
let unzapped = radLevels.removeAt(level);
