Comparison between two NPM packages [closed]

I’d like to compare the performances between two npm packages:

• https://www.npmjs.com/package/row-to-tree
• https://www.npmjs.com/package/performant-array-to-tree

I found this website: https://jsbenchmark.com/

But I don’t understand how I can import the NPM packages in the test cases.
Could anybody help me?

Thanks in advance.
