It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate Language (MSIL).

    INTERNATIONAL JOURNAL OF PROGRESSIVE RESEARCH IN SCIENCE AND ENGINEERING, VOL.2, NO.8, AUGUST 2021. Web Application to Search and Rank Online Learning Resources from Various Sites Keshav J1, Venkat Kumar B M1, Ananth N1 1Student, Department of Computer Engineering, Velammal Engineering College, Anna University, Chennai, Tamil Nadu, India. Corresponding Author: [email protected] Abstract: - E-Learning is becoming one of the most reliable and fast methods for learning in the present days and this trend will only continue to grow in the coming years. However, the process of finding the correct course in the desired topic is becoming harder and harder day by day due to the sheer number of resource material being uploaded to the internet. Currently, whenever there’s a need to acquire a new skill or learn something new, people go on different platforms to search for resources to learn them - YouTube for videos, Google for blogs, Coursera/Udemy/Edx for courses. This leads to taking too much time in finding the right resource to start learning. They have to try out multiple resources before finding the right one. We plan to eliminate this with our website, where a single search query will fetch the top videos, blogs, and courses for that query. Users will be able to rate the results, and the upcoming search results will be ordered primarily based on the user ratings. This will allow the most useful blogs, courses, and videos to rank up. Additionally, the resources will have comments and tags, so that the user can read a review before opening a tutorial.

  • Investigating Reason As a Substitute for Javascript
    DEGREE PROJECT IN COMPUTER ENGINEERING, FIRST CYCLE, 15 CREDITS STOCKHOLM, SWEDEN 2020 Investigating Reason as a substitute for JavaScript AXEL PETTERSSON KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Investigation of Reason as a substitute for JavaScript AXEL PETTERSSON Degree Programme in Information and Communication Technology Date: June 4, 2020 Supervisor: Thomas Sjöland Examiner: Johan Montelius School of Electrical Engineering and Computer Science Host company: Slagkryssaren AB Swedish title: Undersökning av Reason som ett substitut till JavaScript Investigation of Reason as a substitute for JavaScript / Undersökning av Reason som ett substitut till JavaScript c 2020 Axel Pettersson Abstract | i Abstract JavaScript has in recent years become one of the most utilized programming languages for developing different kinds of applications. However, even though it has received a lot of praise for its simplicity, versatility and highly active community, it lacks some functionalities and features that a lot of programmers highly value, like static and strict typing, compile-time debugging, and to not be required to make use of third-party libraries to integrate crucial functionality. However, several new languages built on top of JavaScript have been developed to address and resolve these issues developers find with JavaScript without losing the benefits that come with it. One of these super- set languages is Reason, the new syntax and toolchain powered by the OCaml compiler. This thesis aims to address whether there are scenarios where Reason could act as a reasonable substitute of JavaScript by investigating how the languages compare in regards to different criteria. The criteria examined are writability, data structures and typing, reliability and testing, community support, market demand, portability, and performance.

  • Project Evaluation Report
    Project Evaluation Report Project Title: SMART-bridge-to-WEB School/Department: Design, Creative and Digital Industries/Computer Science and Engineering Project Team: Wesam Makadicy, Tomasz Wasowski, Marius Ignat, Nasro ABdi Hassan Sharif, Adam Ahmed-Keyte, Alexander Bolotov, GaBriele Pierantoni, David Chan You Fee Abstract An analysis of the SMARTEST website [1] node view was conducted to gather what features should be transferred over to SMART-bridge-to-WEB (SB2W). Then, several prototypes were created from the requirements identified during analysis until a final master prototype was developed. This prototype was used as a reference for the project’s implementation, which can be viewed at [2]. The report is concluded by reflecting on our teamworK, how the project went, and on what we will do next with the project. Introduction This project aims at developing a web-based application which will target an additional functionality to the already developed Knowledge and learning platform SMARTEST [1]. The platform, as it currently stands, enables interactions between students and academics, represents learning content graphically in forms of module structures and learning processes. It has attracted more than 300 registered student users both from University of Westminster (UoW) and various groups of students at our partner university in TashKent – Westminster International University in TashKent (WIUT). This is due to it offering a more interactive interface of building learning content in the form of graphs and learning paths [3], which other existing learning platforms such as BlacKboard [4] does not. However, for many student users and academics, specifically for those not from STEM disciplines, the representation of learning content in the form of graphs may not be ideal as it requires an understanding of the additional graph structure/concept.

  • What Is Node.Js? the Javascript Runtime Explained | Infoworld 3/21/21, 6:09 PM
    What is Node.js? The JavaScript runtime explained | InfoWorld 3/21/21, 6:09 PM What is Node.js? The JavaScript runtime explained Node.js is a lean, fast, cross-platform JavaScript runtime environment that is useful for both servers and desktop applications By Martin Heller Contributing Editor, InfoWorld APR 6, 2020 3:00 AM PDT Scalability, latency, and throughput are key performance indicators for web servers. Keeping the latency low and the throughput high while scaling up and out is not easy. Node.js is a JavaScript runtime environment that achieves low latency and high throughput by taking a “non-blocking” approach to serving requests. In other words, Node.js wastes no time or resources on waiting for I/O requests to return. In the traditional approach to creating web servers, for each incoming request or connection the server spawns a new thread of execution or even forks a new process to handle the request and send a response. Conceptually, this makes perfect sense, but in practice it incurs a great deal of overhead. [ Also on InfoWorld: The 10 best JavaScript editors reviewed ] https://www.infoworld.com/article/3210589/what-is-nodejs-javascript-runtime-explained.html Page 1 of 14 What is Node.js? The JavaScript runtime explained | InfoWorld 3/21/21, 6:09 PM While spawning threads incurs less memory and CPU overhead than forking processes, it can still be inefficient. The presence of a large number of threads can cause a heavily loaded system to spend precious cycles on thread scheduling and context switching, which adds latency and imposes limits on scalability and throughput.
