In languages which support first-class functions and currying, map may be partially applied to lift a function that works on only one value to an element-wise equivalent that works on an entire container; for example, map square is a Haskell function which squares each element of a list.
The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
If no value is found, some lookup functions raise an exception, while others return a default value (such as zero, null, or a specific value passed to the constructor). Associative arrays may also include other operations such as determining the number of mappings or constructing an iterator to loop over all the mappings. For such operations ...
Go's foreach loop can be used to loop over an array, slice, string, map, ... to both the key and the value of a map. Here is a forward iteration over the elements of ...
Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.
