isEmoji

isEmoji(value) returns true when value contains at least one emoji, matched against a full Unicode emoji regex (sequences, modifiers, flags, and ZWJ combinations included). It does not require the whole string to be emoji — any emoji anywhere makes it true.

Part of pota/use/string.

Arguments

Argument	Type	Description
value	string	The string to scan.

Returns: boolean — true if value contains any emoji.

Examples

Detect emoji in input

Flags whether the current input value contains an emoji.

import { render, signal } from 'pota'
import { isEmoji } from 'pota/use/string'

function App() {
	const text = signal('hello 🌮')
	const found = () => isEmoji(text.read())

	return (
		<>
			<input
				prop:value={text.read}
				on:input={e => text.write(e.currentTarget.value)}
			/>
			<p>{() => (found() ? 'contains emoji' : 'no emoji')}</p>
		</>
	)
}
