function greaterThan(n) {
    return function(m) {
        return m > n;
    };

var greaterThanTen = greaterThan(10);

var result2 = greaterThanTen(9)

A Higher-Order Function (HOF) in JavaScript is a function that does at least one of the following:

1. Takes one or more functions as arguments.
2. Returns a function as its result.

So, while it's common for higher-order functions to accept other functions as arguments, it's not a requirement. A function can be considered a higher-order function if it returns a function, even if it doesn't accept any function as an argument.
