How to import an un-installed module into javascript?

Question

Hello, I recently saw some code (as I understood it didn't work because sololearn couldn't find the phaser module), who knows how to add a module to js without installing? Or just how to add a third-party module to js in sololearn.

Answer 1

And none answered how to insert without installation._.
I kind of figured it out myself already

Answer 2

You can include a js source file for example in head or body of the html.

Answer 3

But still thanks
