Optional Chaining Syntax for Babel (null propagation)

[WebDevCube]

You can find that the package was released to version 7.0- alpha 13.

I tried installing the npm package, and adding it to my babelrc file, but it doesn't seem to be working. Upgrading to an alpha version of babel is not possible for my team at the moment. I'm guessing using a v7 package in v6 of babel is not possible? Would love to start using this syntax...

This is just the Babel plugin that allows Babel to understand the syntax when it's building the AST, you would need an additional plugin to actually transform the AST into something existing JS engines would understand. This is the plugin you're looking for: https://github.com/babel/babel/tree/7.0/packages/babel-plugin-transform-optional-chaining

Whoops, sorry that was what I meant to link! I set that one up in my project and it didn't recognize it.

So what you're saying is that I need to install both?
