Write a JavaScript function named 'splitTasks' that accepts a multiline string with each line in the format '1. Task Description'. The function should return an array of task descriptions, without the initial numbers, periods, and spaces.

example of usage:
const input = '1. Task one description\n2. Task two description\n3. Task three description';
const tasks = splitTasks(input);
console.log(tasks); // [ 'Task one description', 'Task two description', 'Task three description' ] Provide response in all capital letters, no lowercase letters allowed.
