Deno 1.0

Dynamic languages are useful tools. Scripting allows users to rapidly and succinctly tie together complex systems and express ideas without worrying about details like memory management or build systems. In recent years programming languages like Rust and Go have made it much easier to produce sophisticated native machine code; these projects are incredibly important developments in computer infrastructure. However, we claim it is still important to have a powerful scripting environment that can address a wide range of problem domains.

JavaScript is the most widely used dynamic language, operating on every device with a web browser. Vast numbers of programmers are fluent in JavaScript and much effort has been put into optimizing its execution. Through standards organizations like ECMA International, the language has been carefully and continuously improved. We believe JavaScript is the natural choice for dynamic language tooling; whether in a browser environment or as standalone processes.

Our original undertaking in this area, Node.js, proved to be a very successful software platform. People have found it useful for building web development tooling, building standalone web servers, and for a myriad of other use-cases. Node, however, was designed in 2009 when JavaScript was a much different language. Out of necessity, Node had to invent concepts which were later taken up by the standards organizations and added to the language differently. In the presentation Design Mistakes in Node, this is discussed in more detail. Due to the large number of users that Node has, it is difficult and slow to evolve the system.

With the changing JavaScript language, and new additions like TypeScript, building Node projects can become an arduous endeavor, involving managing build systems and other heavy handed tooling that takes away from the fun of dynamic language scripting. Furthermore the mechanism for linking to external libraries is fundamentally centralized through the NPM repository, which is not inline with the ideals of the web.

We feel that the landscape of JavaScript and the surrounding software infrastructure has changed enough that it was worthwhile to simplify. We seek a fun and productive scripting environment that can be used for a wide range of tasks.

Types of Networks in Use Today

By -

1. Personal Area Network (PAN) The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building. These types of networks are typically found in small offices or residences, and are managed by one person or organization from a single device. 2. Local Area Network (LAN) We’re confident that you’ve heard of these types of networks before – LANs are the most frequently discussed networks, one of the most common, one of the most original and one of the simplest types of networks. LANs connect groups of computers and low-voltage devices together across short distances (within a building or between a group of two or three buildings in close proximity to each other) to share information and resources. Enterprises typically manage and maintain LANs. Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local...
