Hi [Skay](https://hashnode.com/@skay), thanks for the article.

There is an incorrect comment in your code:

```
//Higher order function - takes 'func' as an argument & returns a 'func' for execution
const higherOrderFunction = function(func, a, b) {
    return func(a, b);
}
```

This function is not actually returning a function, but rather the result of the callback function, which is data.

A more concise example might be:

```
const sum = function(a, b) {
    return a + b;
}
//Higher order function - takes 'func' as an argument & returns a 'func' for execution
const higherOrderFunction = (func) => (a, b) => {
    return func(a, b);
}
const sumFor = higherOrderFunction(sum);
console.log(sumFor(2,3));
```

Here, `higherOrderFunction` takes `func` and returns a function, which then takes `a,b` and return data.

Cheers!

[Bob Jones](https://hashnode.com/@crazy4groovy) - Thank you for catching this! While I had intended to convey what you had indicated it, I did not want to use arrow functions and it got a little messy.

I have updated the main section of code, with your code snippet and included additional comments on what the higher-order function returns.

Once again, thank you for catching this. Really appreciate it!!
