Question

Can you show an example of a function with a return statement in a higher-order function?

Answer 1

Yes, a higher-order function is one that can accept other functions as arguments and/or return them as results. Here’s an example in JavaScript:

function higherOrderFunction(num) {

return function addFive() {

return num + 5;

}

}

let result = higherOrderFunction(10);

console.log(result()); // Outputs: 15

In this code, 

higherOrderFunction

 is the higher-order function because it returns another function (

addFive

). The inner function uses a return statement to give back the result of adding five to whatever number was passed into the outer function.
