To ensure the sorting algorithms are generic, they are implemented as functions that take an array of elements and a comparison function as parameters. The comparison function is used to compare the elements in the array and determine their order.
The comparison function should take two parameters and return a number:
- a negative number if the first element is smaller than the second element
- zero if the first element is equal to the second element
- a positive number if the first element is greater than the second element
type CompareFunction<T> = (a: T, b: T) => number;With this approach, the sorting algorithms can be used to sort arrays of any type, as long as the comparison function is implemented correctly.
