That's why I said have both with the emphasis on the one that better expresses it so people know what you're aiming for. I've written FP blog posts in the past with Javascript to accompany just in case it wasn't clear because of syntax. But if you'd just looked at the Javascript, your takeaway will probably be similar to many FP-in-JS articles of 'why so much ceremony?' The 'other' language is merely a bridge. And if you can only communicate from the bridge language's perspective, you won't be able to grasp intermediate topics.
