There is a way to do it where you have very little implicit scope in your loop and do away with extra variables.

var i = 0,
     item;

// note this is weak to sparse arrays or falsey values
for ( ; item = myStringArray[i++] ; ){ 
    item; // This is the string at the index.
}

Or if you really want to get the id and have a really classical for loop:

var i = 0,
    len = myStringArray.length; // cache the length

for ( ; i < len ; i++ ){
    myStringArray[i]; // Don't use this if you plan on changing the length of the array
}

Modern browsers all support iterator methods forEach, map, reduce, filter and a host of other methods on the Array prototype.

OK, seriously do not use the method that includes looking up the length on each iteration.

var i = 0,
     item;

// note this is weak to sparse arrays or falsey values
for ( ; item = myStringArray[i++] ; ){ 
    item; // This is the string at the index.
