Java JavaScript arrays and loops combination question

[mindauggas]

var lost = [4, 8, 15, 16, 23, 42];
var count = lost.length;

var isLost = function (n) {
for (i=lost[0]; i<count; i=lost[i+1]) {
if ( n === lost) {
return "true";
}
}
return "false";
};

is it possible to in corporate array positions into the for loop? (i)
do I even begin to approach the correct "incorporation"? (ii)

As I understand your questions:
(i) Use i = i+1, or i++ as the increment.
(ii) You would want to return the boolean literals true or false instead of their string representation. You may also want to check out the array indexOf operation [1].

You should do something like this to read the contents of an array. Don't forget to declare var i and n (whatever that is):

for(var i = 0; i < lost.length; i++){
    if(n == lost[i]){
        return true;
    }
}

var i in the for loop is the position of the array that you are examining.
