About this Report

WebAssembly is a binary instruction format that provides a portable compilation target for a wide range of programming languages. It aims to take advantage of the common hardware capabilities of a wide range of platforms to enable execution at near-native speeds. The aim of this report is to investigate the current state of this technology. We will explore the languages for which developers use WebAssembly as a compilation target and the performance benefits it provides when migrating their projects. We will also look at aspects that attract developers to WebAssembly, the challenges they face, and how optimistic they are about the future adoption of this technology. Finally, we will conclude by focusing on the WebAssembly System Interface (WASI), gauging familiarity levels and uncovering the key motivations behind its usage.
