In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes. In the client–server model, the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic.
Those scripts were executed by the operating system, and the results were served back by the web server. Many modern web servers can directly execute on-line scripting languages such as ASP , JSP , Perl , PHP and Ruby either by the web server itself or via extension modules (e.g. mod_perl or mod_php ) to the webserver.
A full-stack developer is expected to be able to work in all the layers of the application (front-end and back-end). A full-stack developer can be defined as a developer or an engineer who works with both the front and back end development of a website, web application or desktop application. [ 6 ]
The goal of front-end development is to create a website's user interface and visual components that users may interact with directly. On the other hand, back-end development works with databases, server-side logic, and application functionality. Building reliable and user-friendly online applications requires a comprehensive approach, which is ...
A web developer is a programmer who develops World Wide Web applications using a client–server model. The applications typically use HTML , CSS , and JavaScript in the client, and any general-purpose programming language in the server.
This source code/machine code independence is intended to enable generic optimizations to be shared between versions of the compiler supporting different languages and target processors. Examples of middle end optimizations are removal of useless (dead-code elimination) or unreachable code (reachability analysis), discovery and propagation of ...
It can be used to develop a frontend for any programming language and a backend for any instruction set architecture. LLVM is designed around a language-independent intermediate representation (IR) that serves as a portable, high-level assembly language that can be optimized with a variety of transformations over multiple passes.
