The document presents an overview of webassembly, highlighting its benefits such as speed, portability, and security in web development. It discusses the importance of etiquette during sessions, with specific guidelines on punctuality, feedback, and muting to minimize disturbances. Additionally, it addresses the existing challenges in webassembly, such as manual memory management and debugging, while reiterating its compatibility with major operating systems and browsers.

feedback for all sessions as it is
very helpful for the presenter.
Mute

5. WebAssembly

6. WebAssembly
● New transformation in Web development.
● A new capability to Web and web browsers.
● Fast, portable and secure.
● Safe and Isolated execution and memory.
● Compile to WASM from any supported language
○ C, C++, Go, Rust
● Interpret in Many languages:
○ JavaScript,Node, Go, Rust, C, C++

7. Efficient and Fast
WebAssembly aims to execute at
native speed by taking advantage of
common hardware capabilities
available on a wide range of
platforms.
01
Open and debuggable
WebAssembly is designed to be
pretty-printed in a textual format for
debugging, testing, experimenting,
optimizing, learning, teaching, and
writing programs by hand.
03
Safe
WebAssembly describes a
memory-safe, sandboxed execution
environment that may even be
implemented inside existing
JavaScript virtual machines.
02
Open web platform
WebAssembly is designed to
maintain the versionless,
feature-tested, and
backwards-compatible nature of the
web.
04
WebAssembly features

9. WebAssembly for Web developers
● Existing code to web.
● like Autocad, Various Games, and image processing tools, etc.
● Ecosystem

11. Web Development Today
● Browser Compatibility
● Disparate build
environment
● TypeScript,
JavaScript,
CoffeeScript, X-to-JS
CodeGen.
As SPA’s gets better and
more powerful, gets
everything gets slower.
● Slow builds.
● Bloated Frameworks.
● Code Performance.
● Browser Issues.
● An infinite number of
ways to solve every
problem.
● Too many libraries, too
much to learn
node_module directory
is a meme.
● Rapid ecosystem
change.
Fragmented Slow Overwhelming

13. WebAssembly vs Javascript

14. WebAssembly with Rust
● Get benefit of unique Rust features.
○ Memory safety
○ Efficiency
○ Portability
● Wasm pack, Wasm_bindgen.
● Powerful community.
