Why is listings ignoring my whitespace?

Question

\documentclass{article}

\usepackage{listings}
\usepackage{jslistings}

\begin{document}

Test: \lstinline[language=JavaScript]!import {function} from "@icm/service-name";!

\end{document}

results in

Why does it remove the space between } and from?

Edit: I am using a custom language definition:

Answer 1

The listings package does not support JavaScript. Either you switch to a different package to display your code, or you define it yourself. Fortunately other folks had the same issue and published code.

I took the JavaScript definition below from here: https://github.com/ghammock/LaTeX_Listings_JavaScript_ES6
