You run WebAssembly (or Wasm, for short) for faster performance on browsers like Firefox and Chrome. But how fast and efficient is Wasm?
Learn more about Wasm features below.
Here's how it works: Wasm is an open standard (software that's freely available for any developer to use) that executes binary code on the internet.
Developers can basically do what they want with Wasm, from creating gaming applications in web pages to running it as a language in serverless environments.
Developers can also use this code to execute browser operations with various languages, such as C, C++, and Rust.
The first version of Wasm (WebAssembly 1.0) has shipped in four web browsers:
So far, so good.
But what about speed?
It depends on whom you ask.
Exact speeds depend on various factors, such as the specific browser that executes the Wasm code. However, most benchmarks suggest Wasm is considerably faster than other source codes.
(All speed tests conducted by Aaron Turner via Medium.com.)
Since these two coding languages go head to head with each other, we will share their features that sets them apart from one another.
Because Wasm is a low-level binary format with a small size, it loads faster in web browsers like Firefox, Chrome, and Safari.
When these browsers execute the Wasm code, they fetch it quicker from the server.
Wasm also uses a linear memory and is "statically typed," which means the computer program that translates its code (the "compiler") decides if specific variables perform certain actions.
These factors increase Wasm speeds to a level that's like running binary on the command line.
It's no wonder, then, that so many companies now use Wasm to execute web applications and other functions.
Currently, major companies like Cubbit, Foretag, and Backend have incorporated Wasm into their tech stacks.
Here's what Wasm's creators have to say:
"The design of WebAssembly promotes safe programs by eliminating dangerous features from its execution semantics while maintaining compatibility with programs written for C/C++.
Modules must declare all accessible functions and their associated types at load time, even when dynamic linking is used.
This allows implicit enforcement of control-flow integrity (CFI) through structured control-flow."
So there you have it.
There's no doubt that Wasm is faster than other source codes, and there's lots of research to back this all up.
On the study run by Aaron Turner he found out that;
When you plan to use Wasm on desktop Chrome, which is written in AssemlyScript, for Wasm's Intended use case, then yes, Wasm is around 30% faster.
Whereas on mobile it goes further reaching a 60% faster experience. When it came to Firefox experience it was around 90% faster.
The only time when Wasm was slower than 30% was when tested on safari due to it's JS engine which handled WasmBoy very efficiently.
So many of the world's largest companies, including Google Earth, now use this open standard to execute powerful web applications in browsers.
Wasm is not only fast, but it's safe to use, making it an exceptional fit for developers worldwide.
