Question

function cypherCode(){
var alphaBet = new Array{"a","b","c"};
for(i=0; i<alphaBet.length; i++){
document.write(alpha.Bet[i]);
};
};
cypherCode();

Answer 1

Change your array declaration to
var alphaBet = ["a", "b", "c"];

Answer 2

Write like this
function ds(){
var a=new Array("gh","hdh");
for(var i=0;i<a.length;i++){
document.write(a[i])
}
}
ds();

You can see where your code is different from my code and change.

Answer 3

remove the '.' at 'document.write(alpha.Bet[i]);
(this '.' here -> alpha.Bet)

Answer 4

var alphaBet = ["a", "b", "c"];
function cypherCode() {
for (i=0; i<alphaBet.length; i++) {
document.write(alphaBet[i]);
}
};
var morealphaBet = ["d", "e", "f"];

Array.prototype.push.apply(alphaBet, morealphaBet);
cypherCode();
alert(alphaBet.length);
