How do I find the last index of an array?
Subtracting 1 from the length of an array gives the index of the last element of an array using which the last element can be accessed. The reason we are subtracting 1 from the length is, in JavaScript, the array index numbering starts with 0. i.e. 1st element’s index would 0.
