The classic JS programming language for iPad, iPhone and iPod touch. Programming language is a perfect tool for studying, complex mathematical calculation, entertainment and many other useful tasks. The application is especially useful for learning the JS programming language. You have to buy compilations inside the application. Internet connection is required.

- The great programming tool on the AppStore.
- Your programming language for iOS is amazing!


- Compile and run your program.
- Text input before program run and text output.
- Enhanced source code editor with syntax highlighting, line numbers, color themes and additional keyboard.
- Online language reference and several program samples.


- Internet connection is required to compile and run a program.
- Graphics, network, file system and real-time input are not supported.
- Maximum running time of a program is 15 seconds.

Look for the "PHP Programming Language" on the AppStore too. Thanks for using the application!


JS is a prototype-based scripting language that is dynamic, weakly typed and has first-class functions. It is a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles.

JS was formalized in the ECMAScript language standard and is primarily used in the form of client-side JS, implemented as part of a Web browser in order to provide enhanced user interfaces and dynamic websites. This enables programmatic access to computational objects within a host environment.

JS's use in applications outside Web pages — for example in PDF documents, site-specific browsers, and desktop widgets — is also significant. Newer and faster JS VMs and frameworks built upon them (notably Node.js) have also increased the popularity of JS for server-side web applications.

JS uses syntax influenced by that of C. JS copies many names and naming conventions from Java, but the two languages are otherwise unrelated and have very different semantics. The key design principles within JS are taken from the Self and Scheme programming languages.

JS was originally developed by Brendan Eich of Netscape under the name Mocha, which was later renamed to LiveScript, and finally to JS mainly because it was more influenced by the Java programming language. LiveScript was the official name for the language when it first shipped in beta releases of Netscape Navigator 2.0 in September 1995, but it was renamed JS in a joint announcement with Sun Microsystems on December 4, 1995, when it was deployed in the Netscape browser version 2.0B3.

The change of name from LiveScript to JS roughly coincided with Netscape adding support for Java technology in its Netscape Navigator web browser. The final choice of name caused confusion, giving the impression that the language was a spin-off of the Java programming language, and the choice has been characterized by many as a marketing ploy by Netscape to give JS the cachet of what was then the hot new web programming language. It has also been claimed that the language's name is the result of a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Sun's Java runtime with its then-dominant browser.

In November 1996, Netscape announced that it had submitted JS to Ecma International for consideration as an industry standard, and subsequent work resulted in the standardized version named ECMAScript.

Not a JavaScript tool

This app is labeled as a JavaScript tool, and the first block of code you are presented with is Java code. importPackage( is not JavaScript. Worse yet, in order to run code more than once you have to pay for each “compilation.” JavaScript is an interpreted language. It does not get compiled. This app gets 1 star for false advertising.

Do not buy - does not work

Do not buy this app, I was looking for something i could practice my js on while I was on the train. This couldn't even run a simple console.log

Developer Response ,

You can practice JS while you are on the train! But you must have Internet connection to be able to compiler and run your programs.
