Length is a final variable applicable for arrays. It helps to get the size of the array. "myarr" must be an array. And that - 1reduces the size of array by 1. If you want to get number of characters in a string than you can use length().

I think it can be used to delete a letter from word. Mean it is part of code for backspace button.
