Javascript Array lastIndexOf is an inbuilt function that searches an array for the specified element and returns its position. The search will start backward at the specified position, or the end if no start position is specified, and end the search at the beginning of the array. It returns -1 if an element is not found.

If you want to find a particular character’s position in the array then Javascript lastIndexOf() function is useful for you.

If you want to search an array from the start to end, use the  Javascript array indexOf() method.
