 The **`.lastIndexOf()`** method in JavaScript returns the position of the last occurrence of a specified substring within a [string](https://www.codecademy.com/resources/docs/javascript/strings). If the substring is not found, it returns `-1`. It performs a case-sensitive search and can take an optional starting position from which to begin the search backwards.
