You can pass an optional second parameter to the findIndex method, which represents the starting index from where the method should begin the search.
For example:
const array = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const index = array.findIndex((element) => element > 5, 3);
console.log(index); // Output: 5
In the above example, findIndex will start searching for an element that satisfies the provided condition starting from index 3. It will return the index of the first element that satisfies the condition, which is 5 in this case.
