ObjectScript is a new programming language, faster than PHP and JS
ObjectScript is a new embedded and very lightweight object-oriented open source programming language. ObjectScript extends the capabilities of languages such as JavaScript, Lua and PHP. The syntax is mainly taken from JavaScript, the multiple assignment is from Lua, the work with properties is from PHP.
ObjectScript 0.97-vm2 is faster than PHP 5.3.3 and JS by 34% and 61%, respectively.
Fannkuch algorithm was taken for testing . Quite a convenient test, one function with a parameter, when the parameter is increased by 1, the number of calculations increases about 10 times. Accordingly, the less time spent on the test, the better.

In JavaScript, the full source:
Testing was conducted on the platform: Windows 7, CPU Core i7 2630QM 2Ghz. Fannkuch started with parameter 10 .
ObjectScript 0.97-vm2 is a release assembly with a numeric type of double (with float, it turns out to be about 10% faster, but I don’t give these numbers in the article, because PHP and JS are numeric, double, PHP also has integer type):
output (time is average over 10 iterations):
PHP 5.3.3:
output (time is average over 10 iterations):
JS (parameter 10 is inside test_fannkuch.js):
output (time is average over 10 iterations):
The less time the better.
ObjectScript - 20.099 sec
PHP - 26.853 sec
JS - 32.331 sec
Take the standard time 20.099 and reduce the results to percentages:

Ideas for the language borrowed from JavaScript, Lua and PHP
Goals and objectives of the language: scripting game and program logic, cross portability, web and server development

ObjectScript development time - 2 months
The potential for further optimization in speed has not yet been exhausted, but the current characteristics do not look pretty bad. Apparently with further optimization, you can slow down a bit. I plan to study the binding of different languages and make a really convenient binding C ++ to the OS.
With great pleasure I will get you a job and wrap the API you need in OS :)
PS the project requires investment, on cooperation and just questions, you can safely write to evgeniy.golovin [AT] unitpoint.ru
