Examples

Default behavior (both ignore settings enabled)

Only emojis in plain code/text are highlighted:

const x = "Hello 😀";  // ← emoji ignored (in string)
// Nice work! 🔥       // ← emoji ignored (in comment)
const y = 🎉;          // ← emoji DETECTED (plain code)

Detect emojis in strings only

Set "emojiChecker.ignoreInComments": true and "emojiChecker.ignoreInStrings": false:

const x = "Hello 😀";  // ← emoji DETECTED (in string)
// Nice work! 🔥       // ← emoji ignored (in comment)

Detect all emojis everywhere

Set both to false:

const x = "Hello 😀";  // ← emoji DETECTED
// Nice work! 🔥       // ← emoji DETECTED
