Javascript DOM Manipulation Performance Comparing Vanilla Javascript and Leading Javascript Front-End Frameworks
JavaScript DOM Manipulation Performance Comparing Vanilla JavaScript and Leading JavaScript Front-end Frameworks Morgan Persson 28/05/2020 Faculty of Computing, Blekinge Institute of Technology, 371 79 Karlskrona, Sweden This thesis is submitted to the Faculty of Computing at Blekinge Institute of Technology in partial fulfillment of the requirements for the bachelor’s degree in software engineering. The thesis is equivalent to 10 weeks of full-time studies.

Websites of 2020 are often feature rich and highly interactive ap- plications. JavaScript is a popular programming language for the web, with many frameworks available. A common denominator for highly interactive web applica- tions is the need for efficient methods of manipulating the Document Object Model to enable a solid user experience. Objectives. This study compares Vanilla JavaScript and the JavaScript frameworks Angular, React and Vue.js in regards to DOM performance, DOM manipulation methodology and application size. Methods. A literature study was conducted to compare the DOM manipulation methodologies of Vanilla JavaScript and the selected frameworks. An experiment was conducted where test applications was created using Vanilla JavaScript and the selected frameworks. These applications were used as base for comparing applica- tion size and for comparison tests of DOM performance related metrics using Google Chrome and Firefox. Results. In regards to DOM manipulation methodology, there is a distinct difference between Vanilla JavaScript and the selected frameworks. -

Websites are getting larger in size each year, the median size increased from 1479.6 kilobytes to 1699.0 kilobytes on the desktop and 1334.3 kilobytes to 1524.1 kilobytes on the mobile. There are several methods that can be used to decrease the size. In my experiment I use the methods tree shaking, code splitting, gzip, bundling, and minification. Objectives. I will investigate how using the methods separately affect the loading time and con- duct a survey targeted at participants that works as JavaScript developers in the field. -

Open Source Software As Intangible Capital: Measuring the Cost and Impact of Free Digital Tools Preliminary Draft October 31, 20181 Carol A
Open Source Software as Intangible Capital: Measuring the Cost and Impact of Free Digital Tools Preliminary Draft October 31, 20181 Carol A. Robbins*(1), Gizem Korkmaz (2), José Bayoán Santiago Calderón (3), Daniel Chen (2), Claire Kelling (4) , Stephanie Shipp (2), Sallie Keller (2) Abstract Open source software is everywhere, both as specialized applications nurtured by devoted user communities, and as digital infrastructure underlying platforms used by millions daily, yet its value and impact are not currently measured (with small exceptions). We develop an approach to document the scope and impact of open source software created by all sectors of the economy: businesses, universities, government research institutions, nonprofits, and individuals. We use a bottom-up approach to measure subset of OSS projects and languages, collecting data on open source software languages R, Python, Julia, and JavaScript, as well as from the Federal Government’s code.gov website. Using lines of code and a standard model to estimate package developer time, we convert lines of code to resource cost. We estimate that the resource cost for developing R, Python, Julia, and JavaScript exceeds $3 billion dollars, based on 2017 costs. Applying this approach to open source software available on code.gov results in an estimated value of more than $1 billion, based on 2017 costs, as a lower bound for the resource cost of this software. We analyze the dependencies between software packages through network analysis and estimate re-use statistics. This reuse is one measure of relative impact.

Comparing Javascript Libraries
www.XenCraft.com Comparing JavaScript Libraries Craig Cummings, Tex Texin October 27, 2015 Abstract Which JavaScript library is best for international deployment? This session presents the results of several years of investigation of features of JavaScript libraries and their suitability for international markets. We will show how the libraries were evaluated and compare the results for ECMA, Dojo, jQuery Globalize, Closure, iLib, ibm-js and intl.js. The results may surprise you and will be useful to anyone designing new international or multilingual JavaScript applications or supporting existing ones. 2 Agenda • Background • Evaluation Criteria • Libraries • Results • Q&A 3 Origins • Project to extend globalization - Complex e-Commerce Software - Multiple subsystems - Different development teams - Different libraries already in use • Should we standardize? Which one? - Reduce maintenance - Increase competence 4 Evaluation Criteria • Support for target and future markets • Number of internationalization features • Quality of internationalization features • Maintained? • Widely used? • Ease of migration from existing libraries • Browser compatibility 5 Internationalization Feature Requirements • Encoding Support • Text Support -Unicode -Case, Accent Mapping -Supplementary Chars -Boundary detection -Bidi algorithm, shaping -Character Properties -Transliteration -Charset detection • Message Formatting -Conversion -IDN/IRI -Resource/properties files -Normalization -Collation -Plurals, Gender, et al 6 Internationalization Feature Requirements
