# len Length of a collection or string. For strings this is the CODEPOINT count — multi-byte characters (中, é, ─) count 1 each. Use `bytes/len` when you mean the byte size (buffer sizing, protocol offsets on binary data). ## Syntax

[len $coll]

## Examples

[len @{a b c}]     # 3
[len "a中c"]       # 3   (characters)
[bytes/len "a中c"] # 5   (bytes)

## Returns Number. ## See Also `bytes/len`, `chars/count` (same for strings), `width` (display cells)
