“# ES6: Understand the Differences Between import and require”
challenge I saw a note as below:
Note
The lessons in this section handle non-browser features. import , and the statements we introduce in the rest of these lessons, won’t work on a browser directly…

I don’t know what ‘non-browser features’ means?

It means you need more than a browser to work with these features, usually your backend setup needs to support it. In this case I believe it is Node.js (correct me if I’m wrong).

Without that set up the code wouldn’t normally run in a browser.

I believe this means that not all browsers support import and some other statements – whether that’s earlier versions of browsers or some browsers that don’t support it at all (such as IE). We use a transpiler in these cases like Babel so we can convert ES6 code back into ES5 — we can write ES6 code but the browser will run ES5

Thanks a lot!
I got it.

Just copy Tirjasdyn’s answer and copy your company link.
It’s not a real answer.
That’s for a back link to your company website and SEO purposes, isn’t it?
