Non-strict collections of various types also exist (such as the type Stream, a non-strict linked list), and any collection can be made non-strict with the view method. Non-strict collections provide a good semantic fit to things like server-produced data, where the evaluation of the code to generate later elements of a list (that in turn ...
In programming language theory, lazy evaluation, or call-by-need, [1] is an evaluation strategy which delays the evaluation of an expression until its value is needed (non-strict evaluation) and which also avoids repeated evaluations (by the use of sharing). [2] [3] The benefits of lazy evaluation include:
A non-strict evaluation order is an evaluation order that is not strict, that is, a function may return a result before all of its arguments are fully evaluated. [ 28 ] : 46–47 The prototypical example is normal order evaluation , which does not evaluate any of the arguments until they are needed in the body of the function. [ 29 ]
Scala has been widely used in Data science, [125] while ClojureScript, [126] Elm [127] or PureScript [128] are some of the functional frontend programming languages used in production. Elixir 's Phoenix framework is also used by some relatively popular commercial projects, such as Font Awesome or Allegro (one of the biggest e-commerce platforms ...
For example, reverse :: List a -> List a, which reverses a list, is a natural transformation, as is flattenInorder :: Tree a -> List a, which flattens a tree from left to right, and even sortBy :: (a -> a -> Bool) -> List a -> List a, which sorts a list based on a provided comparison function.

(initval /: list)(func) list.foldRight(initval)(func) (list :\ initval)(func) list.reduceLeft(func) list.reduceRight(func) Scala's symbolic fold syntax was intended to resemble the left- or right-leaning tree commonly used to explain the fold operation, [9] but has since been reinterpreted as an illustration of a toppling domino.

In a strict evaluation of head-to-head results, Ole Miss should earn the bid. ∎ Who has the ‘best’ losses? South Carolina’s three losses came against opponents who are either 8-4 or 9-3.
