Tip Programming with fewer side effects is attractive for many reasons. For example, eliminating unnecessary side effects nearly always reduces the complexity of your code, so it leads to fewer bugs. Another thing experienced functional programmers appreciate is that the programmer or compiler can easily adjust the order in which expressions are computed. A lack of side effects also helps you reason about your code: it is easier to visually check when two programs are equivalent, and it is easier to make quite radical adjustments to your code without introducing new, subtle bugs. Programs that are free from side effects can often be computed on demand where necessary, often by making very small, local changes to your code to introduce the use of delayed data structures. Finally, side effects such as mutation are difficult to use when data is accessed concurrently from multiple threads, as you ll see in 14.

Three looping constructs are available to help make writing iterative code with side effects simple: Simple for loops: for var = start-expr to end-expr do expr done Simple while loops: while expr do expr done Sequence loops: for pattern in expr do expr done All three constructs are for writing imperative programs, indicated partly by the fact that in all cases the body of the loop must have a return type of unit. Note that unit is the F# type that corresponds to void in imperative languages such as C, and it has the single value (). We now cover these three constructs in more detail.

Any program can leak memory (that is, claim system memory and then fail to release it when finished), and the allocation and deallocation of memory are a major concern to developers using unmanaged languages such as C. JavaScript is a memory-managed language, in which a garbage-collection process automatically handles the allocation and deallocation of memory for the programmer. This takes care of many of the problems that can plague unmanaged

must be indented on a new line).

code, but it is a fallacy to assume that memory-managed languages can t generate memory leaks. Garbage-collection processes attempt to infer when an unused variable may be safely collected, typically by assessing whether the program is able to reach that variable through the network of references between variables. When a variable is deemed unreachable, it will be marked as ready for collection, and the associated memory will be released in the next sweep of the collector (which may be at any arbitrary point in the future). Creating a memory leak in a managed language is as simple as forgetting to dereference a variable once we have finished with it. Let s consider a simple example, in which we define an object model that describes household pets and their owners. First let s look at the owner, described by the object Person:

Simple for loops are the most efficient way to iterate over integer ranges. This is illustrated here by a replacement implementation of the repeatFetch function from 2: let repeatFetch url n = for i = 1 to n do let html = http url printf "fetched <<< %s >>>\n" html printf "Done!\n"

20 21

function Person(name){ this.name=name; this.pets=new Array(); }

A person may have one or more pets. When a person acquires a pet, he tells the pet that he now owns it:

This loop is executed for successive values of i over the given range, including both start and end indexes.

Person.prototype.addPet=function(pet){ this.pets[pet.name]=pet; if (pet.assignOwner){ pet.assignOwner(this); } }

The second looping construct is a while loop, which repeats until a given guard is false. For example, here is a way to keep your computer busy until the weekend: open System let loopUntilSaturday() = while (DateTime.Now.DayOfWeek <> DayOfWeek.Saturday) do printf "Still working!\n" printf "Saturday at last!\n" When executing this code in F# Interactive, you can interrupt its execution by using Ctrl+C.
