How do I split a string into an array of characters? [duplicate]

Answer 1

Old question but I should warn:

Do NOT use .split('')

You'll get weird results with non-BMP (non-Basic-Multilingual-Plane) character sets.

Reason is that methods like .split() and .charCodeAt() only respect the characters with a code point below 65536; bec. higher code points are represented by a pair of (lower valued) "surrogate" pseudo-characters.
