Match Emojis with Regular Expressions
When experimenting with unicode property escapes, to identify accented letters in strings, it reminded me of a question I had a few years ago: what is the best way to identify and then replace emojis in a string? I first noticed this practice when using emojis in Facebook -- sometimes Facebook would replace an emoji with one of their own custom images, likely because another device may not support that emoji.
Much the way you can match accented characters, you can use unicode property escapes to match emojis:
const emojis = "😂😂💯".match(/\p{Emoji_Presentation}/gu);
// ["😂", "😂", "💯"]
I've previously seen massive arrays of every emoji ever created, and it may be possible that {Emoji_Presentation} doesn't contain all emojis across all devices, but this regex has matched every case I've come across.
Happy emoji....ing!

![CSS Selection Styling]()
The goal of CSS is to allow styling of content and structure within a web page. We all know that, right? As CSS revisions arrive, we're provided more opportunity to control. One of the little known styling option available within the browser is text selection styling.
Great stuff!
But actually there are quite a few where
Emoji_Presentationdoes not work. Probably most of (all?) marked here as not Emoji_Presentation https://www.unicode.org/Public/UCD/latest/ucd/emoji/emoji-data.txt but Extended_Pictographic or just Emoji..match(/\p{Emoji}/gu);work too well (matching 1-9, # and *) but
.match(/(\p{Emoji_Presentation}|\p{Extended_Pictographic})/gu)seems to do the charm :)
