That means I solve problems. A gunshot ricochets off the truck near the Engineer; he ignores it. Not problems like "What is beauty?
Two more gunshots ricochet off the truck, close to the Engineer's head. He glances briefly at the bullet holes. I solve practical problems. The Engineer takes a bottle of beer from a nearby crate and swigs it as the level 1 Sentry Gun near him swivels round and shoots an unseen Heavy.

Usually, reactive programming languages expect such cycles to be "broken" by placing some element along a "back edge" to permit reactive updating to terminate.
Typically, languages provide an operator like delay that is used by the update mechanism for this purpose, since a delay implies that what follows must be evaluated in the "next time step" allowing the current evaluation to terminate.
Interaction with mutable state[ edit ] Reactive languages typically assume that their expressions are purely functional. This allows an update mechanism to choose different orders in which to perform updates, and leave the specific order unspecified thereby enabling optimizations. When a reactive language is embedded in a programming language with state, however, it may be possible for programmers to perform mutable operations.

How to make this interaction smooth remains an open problem. In some cases, it is possible to have principled partial solutions.

Two such solutions include: A language might offer a notion of "mutable cell". A mutable cell is one that the reactive update system is aware of, so that changes made to the cell propagate to the rest of the reactive program. This enables the non-reactive part of the program to perform a traditional mutation while enabling reactive code to be aware of and respond to this update, thus maintaining the consistency of the relationship between values in the program.
An example of a reactive language that provides such a cell is FrTime. In principle, it is therefore possible for such a library to interact smoothly with the reactive portion of a language. For instance, callbacks can be installed in the getters of the object-oriented library to notify the reactive update engine about state changes, and changes in the reactive component can be pushed to the object-oriented library through getters.

FrTime employs such a strategy. In other languages, the graph can be dynamic, i. For a simple example, consider this illustrative example where seconds is a reactive value: Therefore, the graph of dependencies updates every second. Permitting dynamic updating of dependencies provides significant expressive power for instance, dynamic dependencies routinely occur in graphical user interface GUI programs.Meet the Engineer REACTION
However, the reactive update engine must decide whether to reconstruct expressions each time, or to keep an expression's node constructed but inactive; in the latter case, ensure that they do not participate in the computation when they are not supposed to be active.
Concepts[ edit ] Degrees of explicitness[ edit ] Reactive programming languages can range from very explicit ones where data flows are set up by using arrows, to implicit where the data flows are derived from language constructs that look similar to those of imperative or functional programming.
For example, in implicitly lifted functional reactive programming FRP a function call might implicitly cause a node in a data flow graph to be constructed. Reactive programming libraries for dynamic languages such as the Lisp "Cells" and Python "Trellis" libraries can construct a dependency graph from runtime analysis of the values read during a function's execution, allowing data flow specifications to be both implicit and dynamic.
Sometimes the term reactive programming refers to the architectural level of software engineering, where individual nodes in the data flow graph are ordinary programs that communicate with each other.
Static or dynamic[ edit ] Reactive programming can be purely static where the data flows are set up statically, or be dynamic where the data flows can change during the execution of a program. The use of data switches in the data flow graph could to some extent make a static data flow graph appear as dynamic, and blur the distinction slightly. True dynamic reactive programming however could use imperative programming to reconstruct the data flow graph.
Higher-order reactive programming[ edit ] Reactive programming could be said to be of higher order if it supports the idea that data flows could be used to construct other data flows.
That is, the resulting value out of a data flow is another data flow graph that is executed using the same evaluation model as the first.
Data flow differentiation[ edit ] Ideally all data changes are propagated instantly, but this cannot be assured in practice. Instead it might be necessary to give different parts of the data flow graph different evaluation priorities.
This can be called differentiated reactive programming. The story went viral and earned the steakhouse a reputation that routinely lands them a spot in pieces like this one. To accomplish a similar win, consider implementing social listening software that will alert you to any mentions of your brand online.
For complaints, respond with an apology, a description of what the company is doing to correct the issue and a gift certificate or discount to make up for any inconvenience. Many customers prefer to find answers to their problems themselves rather than having to call or email a company. A Forrester survey even revealed that 57 percent of customers will give up on an online purchase altogether if finding the answer to their question proves too difficult. One of the easiest ways to please customers in search of a solution is to make answers to common questions easy to find.
You can identify these questions by talking to customer service representatives, identifying the most frequent searches performed on your website and reviewing customer service call and email logs.
