How to organize Javascript plugin code in multiple files?

Question

JavaScript

Hello, for the first time I am writing a full-fledged js-component for displaying data in the form of a table and a chart. The code is divided into several files:

• Classes for working with SVG
  
• Class for drawing a chart
  
• The class of the table itself
  

With the help of gulp I concatenate these three files into one.
At the moment, all classes are declared in the global window in order to have access from other files.
Can you please tell me a design pattern that would correctly organize the code so that all classes can be accessed from other files and not litter in the global object?

Answer 1

there are loaders for this, I advise Webpack

Answer 2

Create a prototype that will be the main class of the library, and include everything you need to work in it.
