Bring Native Performance to Your Web Applications

Perhaps you've encountered scenarios where JavaScript performance becomes the bottleneck. Image processing, data analysis, or real-time simulations that work smoothly in native applications struggle when implemented purely in JavaScript, limiting what you can deliver through the browser.

You might have valuable code written in C++ or Rust that could benefit web-based users, but rewriting everything in JavaScript isn't practical or performant. The gap between what desktop applications can do and what web applications can achieve may be constraining your project scope or user experience.

WebAssembly provides a path to bridge this performance gap, but the compilation toolchains, memory models, and integration patterns can feel unfamiliar if you're primarily a web developer. Or if you come from systems programming, the browser environment introduces constraints and opportunities that differ from traditional native development. Understanding how to work effectively within these boundaries requires knowledge that goes beyond documentation.

The program combines systems programming concepts with web-specific considerations. Sessions progress from basic compilation through increasingly complex scenarios, building both your technical skills and your judgment about when WebAssembly makes sense for particular use cases. Each topic includes hands-on implementation, moving from guided examples to independent projects.

Our instructors bring experience implementing WebAssembly in production environments, from porting legacy applications to building new performance-critical features. They share insights about debugging strategies, common pitfalls in memory management, and optimization techniques that make meaningful differences in real applications. This practical knowledge complements the technical instruction.

You'll build several substantial projects throughout the training. These include creating an image processing library with filters and transformations, implementing a physics engine for browser-based games, and developing a CAD tool that handles geometric calculations efficiently. Each project demonstrates different aspects of WebAssembly development and becomes part of your portfolio.

The class structure allows time for working through implementation challenges. When you encounter issues with compilation errors, memory bugs, or performance problems, there's support available to help you understand what's happening and how to resolve it. This guidance accelerates your learning compared to struggling through problems alone.

Learning WebAssembly development requires building comfort with both systems programming concepts and browser-specific constraints. The training progresses methodically, starting with basic compilation and gradually introducing threading, SIMD operations, and optimization techniques. This layered approach ensures you understand each concept before adding complexity.

Each week includes both instructional content and substantial development time. You'll start by compiling simple functions, then build increasingly sophisticated applications. Early projects focus on understanding memory management and JavaScript interop. Later projects incorporate threading and SIMD to demonstrate performance optimization in practice.

Your progress manifests in working applications that showcase WebAssembly capabilities. The image processing library you build handles filters and transformations that would be sluggish in pure JavaScript. The physics engine demonstrates real-time simulation, and the CAD tool shows how geometric calculations can run efficiently in the browser. These tangible results demonstrate your growing capability.

The timeline typically spans several weeks, structured to allow working developers to participate. Sessions build on each other, so consistent attendance helps. The pacing provides time to digest concepts between sessions and practice implementation. Developers who experiment with the technologies between classes often develop deeper understanding and better problem-solving approaches.

If WebAssembly development aligns with where you want to take your technical skills, the next step is reaching out with information about your background and goals. Understanding your current experience with systems programming, web development, and the types of applications you want to build helps us ensure this program fits your needs.

We'll respond with details about upcoming sessions, including the schedule and our Tokyo location. The program runs over several weeks with sessions that build on each other. We'll also address any specific questions about prerequisites, project examples, or technical requirements for your development environment.

Before the first session, we'll provide setup instructions for the development toolchain, including Rust and C++ compilation environments. Having these configured beforehand means you can focus on learning during class rather than troubleshooting installation issues. We're available to help if you encounter setup challenges.

The learning community continues after the formal training. As you apply WebAssembly in your projects, questions often arise about specific performance scenarios or integration challenges. We're happy to provide ongoing guidance as you implement these technologies in practice. The training is the beginning of your WebAssembly journey, not the end of it.
