Script Preparation code:

var letters = ["A", "B", "C", "D", "E", "F"];

Tests:

Default
var copy = letters.slice(); var length = copy.length; for (var i = 0; i < length; i++) { if (copy[i] === "B" || copy[i] === "C") { letters.splice(letters.indexOf(copy[i]), 1); } }
Reverse
var copy = letters.slice(); var length = copy.length; for (var i = length - 1; i >= 0; i--) { if (copy[i] === "B" || copy[i] === "C") { letters.splice(i, 1); } }
Fix
var length = letters.length; for (var i = 0; i < length; i++) { if (letters[i] === "B" || letters[i] === "C") { letters.splice(i, 1); i--; } }
