If you'veused languages like Haskell or OCaml, you must have come across the "fold left"(<code>foldl</code>) and "fold right" (<code>foldr</code>) higher-order functions which implement thispattern. These functions are also [available in Juvix][juvix-folds]. In thisblog post, I describe an iterator syntax I designed for Juvix which allowsexpressing folds (and maps, filters and more) in a readable manner.</p>https://docs.juvix.org/pull-139/blog/iterators.html Tue, 12 Nov 2024 13:01:58 +0000Juvix Docshttps://docs.juvix.org/pull-139/blog/iterators.html Jonathan Cubides inductive-types type-system type-system <h1>Stay Positive</h1><p>Let us explore the concept of strictly positive inductive data types, a critical requirement within the Juvix framework for classifying a data type as well-typed.</p><p>An <strong>inductive type</strong> is considered <em>strictly positive</em> if it either:</p><ol><li>Does not appear within the argument types of its constructors, or</li><li>Appears strictly positively within the argument types of its constructors.</li></ol><p>A name is considered strictly positive for an inductive type if it never appearsin a negative position within the argument types of its constructors. The term<em>negative position</em> denotes instances located to the left of an arrow in a typeconstructor argument.</p>https://docs.juvix.org/pull-139/blog/strictly-positive-data-types.html Tue, 12 Nov 2024 13:01:58 +0000Juvix Docshttps://docs.juvix.org/pull-139/blog/strictly-positive-data-types.html
