How Can I Detect Emojis in JavaScript Using Unicode Properties?

Detecting Emoji in JavaScript Using Unicode Properties

Detecting emojis in JavaScript can be challenging, but unicode properties provide a reliable solution. Unicode escapes allow you to match characters based on their Unicode categories, including emojis.

To detect emojis, use the 'p{Emoji}' property escape, which matches any character in the Emoji Unicode category. For example:

<code class="js">if (/\p{Emoji}/u.test("flowers ???") {
  // Contains an emoji
}</code>

Note that certain characters like '123' are technically emojis, but you may prefer to match only "typical" emojis. In that case, use the 'p{Extended_Pictographic}' property escape, which matches all such characters:

<code class="js">if (/\p{Extended_Pictographic}/u.test("flowers ???") {
  // Contains an extended pictograph (emoji)
}</code>

Don't forget to include the 'u' flag to enable Unicode support in your regular expressions. By using Unicode properties, you can effectively detect emojis in JavaScript, ensuring your input validations or filtering mechanisms remain accurate.
