Python 3.7+ vs ES2018+ Syntax Comparison

Python 3.7+ vs ES2018+ Syntax Comparison


This gist is meant to outline differences in syntax and performing common operations in both Python and Javascript (ES2018). This gist may not cover absolutely everything, so a quick double check with Google or StackOverflow can be a big help.

This gist will not cover the extreme basics of the language (i.e. array indexing) because many of these things are intuitive or just common across most languages.

Many of these newer ES2018+ language features might not be available in all browsers. It’s best to use a transpiler/compiler like Babel or Typescript to generate browser compatible code.

Using MSYS2 with Visual Studio Code

Using MSYS2 with Visual Studio Code is extremely easy now thanks to the Shell Launcher extension by Tyriar.

First, install the extension and reload Visual Studio Code.

Then, open the settings.json to edit your settings.

Add the field I recommend using autocompletion here so that all the default shells are added.

You should having something like this now:
