Convert Javascript to Python and vice versa easily with these tools
With these tools you can convert your code written in one language to its equivalent in another
Javascript and Python, both are high level object oriented languages. Programmers prefer Python over other similar languages because it allows them to express concepts in fewer lines of code. Whereas Javascript is the major scripting language used on World Wide Web . Which one out of these two is going to rule in the upcoming future, is a topic of debate among tech geeks.
JavaScript is quite welcoming as a target language for others to be converted into, and Python’s wealth of large number of existing libraries make it a good candidate for “transpiling” to Javascript.
Here are four major projects which are working in this direction and can be used for cross compilation.
What they do: You write a code in one language, compile it by one of the tools listed below and an equivalent code of another language is generated.
The list follows :
Transcrypt
A newly minted Python-to-JS transpiler, Transcrypt makes intriguing promises about the quality of the code it generates. For one, it attempts to preserve the structure of the original Python code as closely as possible, including the likes of multiple inheritances and lambdas. The source Python code can also make calls to objects in JavaScript’s namespace as-is. If you try to access document.getElementById in Python, the converted code will use the actual document.getElementById in Javascript.
According to the documentation, Transcrypt accomplishes these tasks with CPython’s Abstract Syntax Tree module, which allows programmatic access to the way Python parses its own code. Though the project is still in alpha, it’ll be fascinating to see how it shapes up.
Jiphy
Jiphy converts in both directions, plus one can intermix codes from both languages before converting into target language. Even though Jiphy stands for “Javascript in Python out”.
The biggest drawback to Jiphy right now is that it supports only a subset of Python’s features. Classes or default arguments aren’t available yet, although decorators and exceptions are. Much of this is because Jiphy insists on establishing as close to a line-to-line relationship as possible between the source and target code, but its developers are eyeing the new features in ES6 for more advanced Python feature support.
Brython
Brython implements a version of Python 3 for client-side Web programming via a JavaScript library that emulates all the keywords and most of the built-ins for Python 3. Scripts written in Python can be included directly in a Web page, and Brython supplies a high-level Python module interface (browser) for performing the work with the DOM and the browser normally done directly.
However, Brython also maintains the restrictions imposed on JavaScript in the browser — for example, there’s no support for dealing with the local filesystem.
RapydScript
RapydScript promises “Pythonic JavaScript that doesn’t suck.” The project is conceptually similar to CoffeeScript: Take in code written in a flavor of Python, generate JavaScript, and leverage the best of both words. In Python’s case, it’s the cleanliness of syntax; in JavaScript’s case, it’s anonymous functions, manipulation of the DOM, and being able to use existing JavaScript libraries like jQuery or the Node.js core.
While these tools give the facility to convert codes, different programmers may have different favorite programming language. You can tell your favorite one in the comments.
