Expression Trees 1 Dynamic Language Runtime Overview 5 Creating and Using Dynamic Objects 9 Early and Late Binding 17 Execute Expression Trees 19 Modify Expression Trees 21 Use Expression Trees to Build Dynamic Queries 23 Debugging Expression Trees 26 Expression Trees (Visual Basic) https://msdn.microsoft.com/en-us/library/mt654260(d=printer).aspx Expression Trees (Visual Basic) Visual Studio 2015 Expression trees represent code in a tree-like data structure, where each node is an expression, for example, a method call or a binary operation such as x < y . You can compile and run code represented by expression trees. This enables dynamic modification of executable code, the execution of LINQ queries in various databases, and the creation of dynamic queries. For more information about expression trees in LINQ, see How to: Use Expression Trees to Build Dynamic Queries (Visual Basic) . Expression trees are also used in the dynamic language runtime (DLR) to provide interoperability between dynamic languages and the .NET Framework and to enable compiler writers to emit expression trees instead of Microsoft intermediate language (MSIL). For more information about the DLR, see Dynamic Language Runtime Overview . You can have the C# or Visual Basic compiler create an expression tree for you based on an anonymous lambda expression, or you can create expression trees manually by using the System.Linq.Expressions namespace. Creating Expression Trees from Lambda Expressions When a lambda expression is assigned to a variable of type Expression(Of TDelegate) , the compiler emits code to build an expression tree that represents the lambda expression. The Visual Basic compiler can generate expression trees only from expression lambdas (or single-line lambdas). -

Topic 14: Client- Side Rendering CITS3403 Agile Web Development Reading: The Flask Mega-Tutorial, part 14 Semester 1, 2021 Miguel Grinberg https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xiv-ajax Accessing a REST API • A REST API takes your application from the web to the internet. Any device with TCP/IP can interact with the application through HTTP requests. • We can interact with a REST API through a number of mediums: command line, Postman, or a web browser. • These applications create and send http requests to the REST API and receive http responses. • Postman can also be used for mocking APIs and automated testing. Javascript and DOM • As a simple example of consuming a REST API we will look at writing a low level single page application that interacts directly with the API. • It will use AJAX to send and receive requests from the server. • It will use Javascript and DOM to update the web page. • We will (redundantly) include it with an existing server-side rendering app. Single Page Applications • Single Page Applications have the browser/client do the heavy lifting in a web application: The server just provides the data while the client does the logic and rendering AJAX AJAX = Asynchronous JavaScript And XML. • AJAX is not a programming language. • AJAX just uses a combination of: – A browser built-in XMLHttpRequest object (to request data from a web server) – JavaScript and HTML DOM (to display or use the data) • AJAX is a misleading name. AJAX applications might use XML to transport data, but it is equally common to transport data as plain text or JSON text. -
Optimizing Runtime Performance of Dynamically Typed Code
Optimizing Runtime Performance of Dynamically Typed Code Jose Quiroga Alvarez PhD Supervisor Dr. Francisco Ort´ınSoler Department of Computer Science University of Oviedo A thesis submitted for the degree of Doctor of Philosophy Oviedo, Spain April 2016 Acknowledgements This work has been partially funded by the Spanish Department of Science and Technology, under the National Program for Research, Development and Innovation. The main project was Obtaining Adapt- able, Robust and Efficient Software by including Structural Reflection to Statically Typed Programming Languages (TIN2011-25978). The work is also part of the project entitled Improving Performance and Robustness of Dynamic Languages to develop Efficient, Scalable and Reliable Software (TIN2008-00276). I was awarded a FPI grant by the Spanish Department of Science and Technology. The objective of these grants is to support gradu- ate students wishing to pursue a PhD degree associated to a specific research project. This PhD dissertation is associated to the project TIN2011-25978 (previous paragraph). This work has also been funded by Microsoft Research, under the project entitled Extending dynamic features of the SSCLI, awarded in the Phoenix and SSCLI, Compilation and Managed Execution Request for Proposals. Part of the research discussed in this dissertation has also been funded by the European Union, through the European Regional Development Funds (ERDF); and the Principality of Asturias, through its Science, Innovation Plan (grant GRUPIN14-100). Abstract Dynamic languages are widely used for different kinds of applications including rapid prototyping, Web development and programs that require a high level of runtime adaptiveness. However, the lack of compile-time type information involves fewer opportunities for com- piler optimizations, and no detection of type errors at compile time. -
The Jasper Framework: Towards a Platform Independent, Formal Treatment of Web Programming
The Jasper Framework: Towards a Platform Independent, Formal Treatment of Web Programming James Smith Imperial College London, United Kingdom [email protected] This paper introduces Jasper, a web programming framework which allows web applications to be developed in an essentially platform indepedent manner and which is also suited to a formal treat- ment. It outlines Jasper conceptually and shows how Jasper is implemented on several commonplace platforms. It also introduces the Jasper Music Store, a web application powered by Jasper and imple- mented on each of these platforms. And it briefly describes a formal treatment and outlines the tools and languages planned that will allow this treatment to be automated. 1 Introduction These days a web application may span both server and client side. Facebook is a good example, with much of the site’s functionality being implemented using JavaScript and executed in the browser. Com- munication between client and server sides is also, typically, not just characterised by requests from the browser, requests are also made by JavaScript in the form of Ajax calls. It is not at all obvious, for example, that Facebook fakes conventional browser requests. Clicking on menu items appears to result in such conventional requests being made, since the whole page seems to change, but in fact these are often Ajax calls and the whole page is changed dynamically, rather than a new page being served. In this way the chat pane can remain “on top”, while the page changes “underneath”. Such techniques used to characterise what were known as rich web applications but they are becoming so commonplace nowadays that a rich web application might be considered the norm. -

For example, you probably understand how encapsulation and implementation-hiding can increase the cohesion of classes. Languages like C# and Visual Basic are excellent for creating so-called coarsely grained types because they expose simple features for grouping and hiding both code and data. You can use cohesive types to raise the abstraction level across a system, which allows for loose coupling to occur. Systems that enjoy loose cou- pling at the top level are much easier to maintain because each subsystem isn’t as dependent on the others as they could be in a poor design. Those benefits are realized at the lower levels, too, typically through lowered complexity and greater reusability of classes. In figure 1.1, which of the two systems depicted would likely be easier to modify? Without knowing what the gray circles represent, most developers would pick the diagram on the right as the better one. -
