Sciter.JS – Sciter but with QuickJS on board instead of my TIScript
Script
Sciter.JS uses QuickJS

  • ES6: async/await, classes, modules, destructuring;
  • BigInt, BigFloat, BigDecimal – arbitrary precision IEEE 754 floating point operations and transcendental functions with exact rounding (currency, etc);
  • Node.JS runtime (more or less full) is coming;

Platforms

  • Windows – i32, i64 and arm64 – published;
  • MacOS – i64 and arm64 – pending;
  • Linux – i64, arm32, arm64 – pending;
  • Mobiles – pending;

Demo
Browser and Sciter shows the same HTML document.
To run demo start run-calculator-browser.bat or run-calculator-sciter.bat. The later will start bin.win/x32/scapp.exe – standalone Sciter engine.

Window
There is no concept of Window in browser sense. Window there is quite strange entity that has no relation with desktop windows.
Instead Sciter.JS will offer Sciter.window object that represents current desktop window with these properties and attributes
import{window}from’Sciter’;// current windowwindow.move(10,10,800,600);
