Det mesta av all information som hittas på nätet som inte är i löpande text, presenteras ofta i tabeller. För att stora tabeller ska vara lättare att hitta i för användaren görs de ibland interaktiva, dvs att de går att sortera efter vald kolumn eller att de går att söka i. När en interaktiv tabell ska implementeras i en webbapplikation kan olika tekniker användas, bland annat JavaScript eller olika MVC-ramverk. I följande tekniska experiment undersöks vilken betydelse val av ramverk gör för exekveringstiden vid sorteringar av tabellens innehåll, och hur tabellens storlek påverkar sorteringens tid. Ramverken har även jämförts med handskriven JavaScript. De två MVC-ramverk som testats är AngularJS och Backbone.js. Resultatet av olika tester som genomförts i experimentet visar att det spelar stor roll vilket ramverk som väljs för detta. Av de ramverk som testats utför webbapplikationen skriven med AngularJS sorteringarna snabbast.

JavaScript is today’s most common client-side programming language for the web. Choosing the most adapted framework for each and every project can optimize the development process and increase profits. Developers often lack knowledge about what to prioritize when choosing a framework and very little previous research regarding this subject area is available. This thesis investigates two JavaScript client-side frameworks and answers the questions of why you should use a framework when developing applications. This thesis also investigates why a company should develop a new framework, when equivalent open-source alternatives are available. To be able to answer the questions interviews with developers were conducted. The results are that using a framework can optimize the development process regarding time and complexity, but learning a new framework can be difficult. In rare cases it is a great idea to develop a new framework for a certain project, but it is often not worth it. Developers also seem to choose experience of using a framework over performance.

JavaScript is used on the web together with HTML and CSS, in many cases using frameworks for JavaScript such as jQuery and Backbone.js. This project is comparing the speed and memory allocation of the programming language JavaScript and its two most used frameworks as well as the language on its own. Since JavaScript is not very fast and it has some missing features or features that differ from browser to browser and frameworks solve this problem but at the cost of speed and memory allocation, the aim is to find out how well JavaScript and the two frameworks jQuery and Backbone.js are doing this on Google Chrome Canary. The results varied (mostly) between the implementations and show that the to-do application is a good enough example to use when comparing the results of heap allocation and CPU time of methods. The results where compared with their mean values and using ANOVA. JavaScript was the fastest, but it might not be enough for a developer to completely stop using frameworks. With JavaScript a developer can choose to create a custom framework, or use an existing one based on the results of this project.

Ever since the late 1950's, context-free grammars have played an important role within the field of linguistics, been a part of introductory courses and expanded into other fields of study. Meanwhile, data visualization in modern web development has made it possible to do feature rich visualization in the browser. In this thesis, these two developments are united, by developing a browser based app, to write context-free grammars, parse sentences and visualize the output. A user experience study with usability-tests and user-interviews is conducted, in order to investigate the possible benefits and disadvantages of said visualization when writing context-free grammars. The results show that data visualization was limitedly used by participants, in that it helped them to see if sentences were parsed and, if a sentence was not parsed, at which position parsing went wrong. Future improvements on the software and studies on them are proposed as well as the expansion of the field of data visualization within linguistics. / Ända sedan det sena 1950-talet har kontextfria grammatiker spelat en viktig roll hos lingvistiska teorier, används i introduktionskurser och expanderats till andra forskningsfält. Samtidigt har datavisualisering inom modern webbutveckling gjort det möjligt att skapa innehållsrik visualisering i webbläsaren. I detta examensarbete förenas dessa två utvecklingar genom utvecklandet av en webbapplikation, gjord för att skriva kontextfria grammatiker, parsa meningar och visualisera utdatan. En användarbarhetsstudie utförs, bestående av användartest och användaintervjuer, för att undersöka möjliga fördelar och nackdelar av visualisering i skrivandet av kontextfria grammatiker. Resultaten visar att data visualisering användes på ett begränsat sätt av deltagarna, i den meningen att det hjälpte dem att se om satser kan parsas och, om en sats inte blir parsad, se på vilket stället parsning misslyckades. Framtida förbättringar av applikationen och studier av dem föreslås samt en utbyggnad av data visualisering inom lingvistik.

This project is devoted to using of agile methodologies in the process of the web development. First, the most widely used traditional and agile methodologies of the software development are theoretically examined. Based on the identified procedures are chosen those that solve the biggest problems associated with the project management of the web development. From the findings is given a rough design of the system with usage of agile procedures. In the final part of the project is mentioned design implemented as the system prototype.
