Variables from the JavaScript side can be evaluated on the Python side, and Python objects can be used from JavaScript code as well. You can import existing Node.js modules in your Python code, by way of a js2py.require method. JS2Py supports a great deal of cross-interoperation between Python and JavaScript. It has official support only for ES5 right now, although there’s experimental ES6 support for the brave and bold.

JS2Py converts JavaScript to Python, as the name implies, using a pure-Python conversion engine. Jiphy should be considered strictly experimental until work on it resumes. Note that the Jiphy project hasn’t been updated since late 2017. Much of this is because Jiphy strives for a line-to-line relationship between the source and target code, but its developers have eyed the new features in ES6 for more advanced Python feature support. Neither classes nor default arguments are available, although decorators and exceptions are supported. The biggest drawback to Jiphy is that it supports only a subset of Python’s features. Rather, its function is, as the README puts it, “to reduce the context switching necessary for a Python developer to write JavaScript code and vice versa.” The Jiphy name is an abbreviation of “JavaScript in, Python out.” In other words, Jiphy converts in both directions between the two languages. Plus, code from both languages can be intermixed before being converted to either target language.īefore you dive in and start converting all of OpenStack to JavaScript, take heed: Jiphy is not about full-blown codebase conversion. Note that the last commits to the JavaScripthon project were in May 2018, so it hasn’t received support for the latest Python features such as the “walrus operator.” But anyone using Python 3.6 features should be well supported. You can also insert JavaScript inline via a special function call, if you ever need to drop down to JavaScript directly. Most of Python’s common keywords and behaviors are supported, including async and await, Python 3.6 f-strings, and Python class methods and inheritances. It emits ES6 code to minimize the need for polyfills on the browser side, and plays well with tools like Webpack by preserving source maps.

JavaScripthon focuses strictly on translating Python 3.5 and later code to JavaScript, without trying to provide full in-browser support as per projects like Brython. There is, however, support for using HTML5 local storage, if all you need is some way to persist data on a per-application basis. For example, there is no support for dealing with the local file system.

It’s even possible to use Brython to write a native Android app in Python. Async functionality is available, although you have to use Brython’s async module instead of Python’s asyncio.īrython does not escape the restrictions imposed on JavaScript in the browser. Plenty of live code examples and a gallery of mini-applications demonstrate how it all works. to handle all of the work normally done directly in JavaScript. Brython supplies a high-level Python module interface (the browser package) to interact with the DOM and the browser, i.e. Scripts written in Python can be included directly in a webpage. The philosophy behind Brython, at least as far as Python 3 is concerned, is why wait?īrython implements a version of Python 3 for client-side web programming via a JavaScript library that emulates all of the keywords and most of the built-ins for Python 3. One of the promises WebAssembly makes is to allow us to use any language we choose to develop for the web, though this remains a distant goal. One stands out by being able to convert in both directions. Here are four current projects for making Python useful in the JavaScript world. And Python’s huge following and wealth of available libraries make it a great candidate to be converted, i.e. Well, maybe not nothing. JavaScript is a favorite target language for “transpilers” that convert one programming language into another (see: TypeScript, Emscripten, Cheerp, Cor).

It’s JavaScript in the browser or nothing. Python or JavaScript? While we’re still arguing over which has the upper hand or the brighter future, little doubt exists as to which owns the web’s front end.
