In JavaScript, the findLastIndex() method is used to find the last index of an array element that satisfies a given condition. It works similarly to findIndex(), but it starts searching from the end of the array instead of the beginning.
array.findLastIndex(callback(element, index, array));
callback: A function that runs for each element in the array.
element: The current element being checked.
index: The index of the current element.
array: The entire array being searched.
