In order to understand how a framework like Frogui is possible, it is useful to understand a recent extraordinary development in web standards, WebAssembly.

​

Web development from the beginning has been very challenging for developers, who dealt with browser incompatibilities and a cascade of trendy frameworks.

​

Things improved dramatically when HTML5 and CSS3 were introduced, bringing unprecedented power to web developers, and the promise of cross-browser compatibility. However, JavaScript still remained the only language option.

​

Outstanding development languages, such as C++, Java and C#, were not welcome to the web. And since JavaScript is interpreted, poor performance was guaranteed relative to native compilation.

​

Fortunately, the WebAssembly standard already exists in all major browsers as of mid-2017 and is revolutionizing web development. It is presently being exploited by C++ and Rust developers, resulting in native browser app performance on par with their non-browser counterparts, all without JavaScript. Other compiled languages, such as C# are not far behind.
