Is it possible to load specific files only when the current route requires them?

Hi. I have an app that uses old .js files from a previous development of my website (in jQuery) which I'm introducing to this project as I'm redesigning my website and only want to load the old apps I made without having to go through the ordeal of re-coding them again to fully match ReactJS standards. It all works, however since each of these apps used a separate .js file to function, I have pasted them into the project as new files, and now when I load the homepage (localhost:3000), all the resources that are mentioned on these javascript files are loaded along with it (even if only a few bytes of each), not on the page body, but on the Network tab of the Chrome developer tools, and I assume into a similar location in other browsers, which would consume memory. Is there a way to tell React not to load these specific files unless the component that uses functions from them requires them?

Is this even the right place to ask this question? Please let me know, and I'll close the issue and ask in a more appropriate location
