Title: In/fi
| Old | New | Line | |
|---|---|---|---|
| 1 | + | [[Reserved word/fi|Varattu sana]] `in` testaa kuuloko kyseinen arvo [[Set/fi|joukkoon]]. Se palauttaa [[Boolean/fi|boolean]] arvon [ `true`](</index.php?title=True/fi&action=edit&redlink=1> "True/fi \(page does not exist\)") jos arvo kuuluu joukkoon ja arvon [[False|`false`]] jos se ei kuulu kyseiseen joukkoon. `In` sanaa käytetään myös varatun sanan [`for`](</index.php?title=For/fi&action=edit&redlink=1> "For/fi \(page does not exist\)") kanssa [[for-in loop|for-in -silmukassa]]. | |
