I was just thinking back to the good old days when I used to

  • 0

I was just thinking back to the good old days when I used to use VBScript (good old days?!?!? What am I thinking?), and I remember using two very useful methods with arrays, these were UBound and LBound. Now I don’t think JavaScript has these and if I wanted to make my own I could extend the object however, I just tried doing this to return the upperbound item (or the last item of the array)

var myArray = ['1','2','3','4','5','6','seven', 8, 'nine','10'];
document.write(myArray.length + ' ' + myArray[myArray.length]);

the myArray.length returns what it should however when I try and output the last item using myArray[myArray.length] I get undefined? Anyone know why this is?

Thanks

    The indexes start at 0. The last element is at myArray.length - 1
