Perf4JS: Automatically Fixing Performance Problems in Real-World JavaScript Applications

• Applicant: Professor Dr. Michael Pradel
• Subject Area: Software Engineering and Programming Languages
• Term: from 2017 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 383433544

• Final Report Year: 2022

Final Report Abstract

In summary, the Perf4JS project has been very successful. The project has enabled significant scientific contributions that advance the state of the art in program analysis, especially in the web and with a focus on software performance. Beyond the original goals, the project has served as seed funding for a direction not anticipated when writing the proposal, namely the analysis of WebAssembly software. WebAssembly is becoming increasingly prevalent in practice and complements JavaScript with a language for the web that focuses on performance. Studying and analyzing WebAssembly software is an important contribution to the original goal of improving the performance of web applications.
