"We had'Javascript for Dummies'books on our desks,"Johnson recalls.""We were figuring it all out on the fly."

Its educational Javascript teaching software targets the six-to 13-year-old age-range and can be played either as a web app via the Code Kingdomssite,

which strips out the gameplay element entirely so it becomes purely a simplified educational tool for teaching Javascript;

Javascript is its programming language. Over the years, however, wee seen more and more efforts that allow developers to work around some of the limitations of Javascript by building compilers that transpile code in other languages to Javascript.

Some of these projects focus on adding new features to the language (like Microsoft Typescript) or speeding up Javascript (like Mozilla asm. js project.

Now, many of these projects are starting to come together in the form of Webassmbly. The new format is meant to allow programmers to compile their code for the browser (currently the focus is on C/C++,

where it is executed then inside the Javascript engine. Instead of having to parse the full code,

Javascript files are simple text files that are downloaded from the server and then parsed and compiled by the Javascript engine in the browser.

The Webassembly team decided to go with a binary format because that code can be compressed even more than the standard Javascript text files

and because it much faster for the engine to decode the binary format (up to 23x faster in the current prototype) than parsing asm. js code, for example.

In this early stage, the team also plans to launch a so-called polyfill library that will translate Webassembly code into Javascript

As Javascript inventor (and short-term Mozilla CEO) Brendan Eich points out today, once the main browsers support the new format natively,

Javascript and Webassembly will be able to diverge again. The team notes that the idea here is not to replace Javascript, by the way,

but to allow many more languages to be compiled for the Web. Indeed, chances are that both Javascript

and Webassembly will be used side-by-side and some parts of the application may use Webassembly modules (animation, visualization, compression, etc.),

while the user interface will still be written mostly in Javascript, for example. It not often that we see all the major browser vendors work together on a project like this,
