This paper analyzes the effectiveness of the Tree-Shaking mechanism, which is a key way to optimize the size of client web applications. Its implementation is compared in five popular tools for building projects: Webpack, Rollup, Parcel, Vite and Esbuild. Test results demonstrate differences in their behavior and overall effectiveness in removing redundant code, highlighting the relevance of Tree-Shaking in web development.

In the world of web development, there is a growing need for tools that can provide high performance for client applications. In response to this challenge, WebAssembly technology has been developed to compile various programming languages into a binary format that can be executed in web browsers. The new AssemblyScript programming language provides the ability to create high-performance WebAssembly modules using the TypeScript language syntax familiar to Web developers. This paper investigates WebAssembly and AssemblyScript, and compares the performance of AssemblyScript and JavaScript using four computational algorithms as examples. The test results demonstrate faster execution speed of AssemblyScript in most tasks, as well as more stable performance when executed in different browsers. The study highlights the relevance of using AssemblyScript to optimize computationally intensive operations in web application development.
