JSlab1.0

JSlab evaluates JavaScript code in an Android browser context, giving users a more capable way to perform calculations than the calculator included with Android. Users can enter JavaScript expressions and execute them through the app’s evaluation environment, using the language’s syntax for calculations and programmable logic.

The app is built around Android WebViews, which supply JavaScript execution, together with the eval() function that runs the supplied code. JavaScript is Turing complete, so JSlab can serve both as an advanced calculator and as a compact place to test small pieces of JavaScript. It suits developers checking expressions or browser-oriented code and users who need calculations that go beyond fixed calculator operations.

JSlab is open-source Developer Tools software for Android, and it runs on Android 5.0 or later. Its universal architecture supports the Android device architectures covered by that build. Version 1.0 is the initial release, introducing the application’s JavaScript evaluation workflow.
