Access last element of a TypeScript array

Is there a notation to access the last element of an array in TypeScript? In Ruby I can say: array[-1]. Is there something similar?

Solution

  • You can access the array elements by its index. The index for the last element in the array will be the length of the array-1 (as indexes are zero based).

    This should work:

    var items: String[] = ["tom", "jeff", "sam"];

alert(items[items.length-1])

    Here is a working sample.
