Developer Timothy Crosley has put together a tiny Python module that can go over Python files and convert the code into their analogue JavaScript syntax and vice versa.

The module, codenamed Jiphy, is not a fully functional Python-to-JavaScript and JavaScript-to-Python compiler that can take fully working applications and migrate them to another platform.

As Mr. Crosley puts it, "Jiphy enables Python programmers to more easily write JavaScript code by allowing them to use more familiar syntax, and even JavaScript developers to more easily write Python code."

This allows developers familiar with one language syntax more than with the other to write the code in the syntax they have a better grasp of, and then convert it into the other after they're done.

As for features, Jiphy has been created to cut down the overhead needed to convert files from one syntax to another, use 1:1 line mappings instead of source maps, and to be used by one single individual without having to change team collaboration procedures inside a company's dev department.

Additionally, Jiphy has also been simplified, so it can be easily integrated into various IDEs as a plugin and made to work with multiple files at once.

You can take a look at the project and its Python-JavaScript line mappings on its Python Package Index page.
