Is there any particular reason for using standard function syntax instead of the arrow one in HOC?

React docs use it too, instead of arrow syntax. I wonder why - is it because of potential complications with "this" keyword when using arrow or just because standard function syntax is convenient (with arrow you can't write export default const withContext = () => {}, so you have declare function before export default keyword)?

Arrow functions do not create their own bindings to the "this" like conventional functions do. MDN suggests that "Arrow function expressions are ill suited as methods".

For more detains, see the MDN page on Arrow functions.

Thanks but I'm asking if is there any particular reason not to use arrow functions in React's HOC , not about general purpose of arrow functions.

Understood, I was thinking the difference in behavior might be such a reason.
