JavaScript Array splice vs slice

Question

What is the difference between splice and slice?

$scope.participantForms.splice(index, 1);
$scope.participantForms.slice(index, 1);         


        

Answer 1

Another example:

[2,4,8].splice(1, 2) -> returns [4, 8], original array is [2]

[2,4,8].slice(1, 2) -> returns 4, original array is [2,4,8]
