Where to include script of gridester.js in react components?

Question

I'm simply trying to execute normal gridster.js in react to create some movable and resizable grids. But My problem is I don't know where to add script and how can I import those js files. in their official site the created gridder.js and gridster.js as two different files but how we can include jquery.gridster.js and where it can be placed in my folder? and one more thing is how we can combine that downloaded git with our program? how to write jquery code and where it should be placed?

Please help with this.[
