'''Jelly''' is an APL-like language inspired by [[J]]. It extends J with many built-ins intended to give Jelly an advantage in [[code golf]], e.g. divmod, the hash function, and string compression. Jelly uses different terminology from normal APL usage. | '''Jelly''' is an APL-like language inspired by [[J]]. It extends J with many built-ins intended to give Jelly an advantage in [[code golf]], e.g. divmod, the hash function, and string compression. Jelly uses different terminology from normal APL usage. Built-in functions are called ''atoms'', while derived functions are called ''links''. Newlines or statement separators are used to separate links, the last line of the program (''chain'') is called the main link. | ||

* Like APL, Jelly uses a wide range of Unicode [[glyph]]s. However, Jelly extends the glyph set to 256 characters from the US International keyboard, as well as the addition of 2-character digraphs. | * Like APL, Jelly uses a wide range of Unicode [[glyph]]s.

* Unlike any other language in the APL family, Jelly atoms have a fixed [[valence]], making Jelly appear more like a stack-based language, and obviating the need for parentheses. | * Unlike any other language in the APL family, Jelly atoms have a fixed [[valence]], making Jelly appear more like a stack-based language, and obviating the need for parentheses. | ||
Some constructs clearly show Jelly lineage through J to APL, e.g. summation can be written as <code>+/</code> (although Jelly also has a dedicated built-in for this). | |||
