Question about javascript function structure

Question

I have a codebase of javascript that I am working on, and have encountered a piece of structure that I am not familiar with. I would just like the name of it so I know what to look up and read about. Any additional information is appreciated.

This is in a Node.js/express environment.

What I'm specifically asking about is the fizz thing in file2.js, referenced in the line marked with a /*!!*/ in file1.js. It looks like some sort of wrapper around a series of functions. What is its proper name?

//file1.js

const file2 = require('filepath/file2')

foo.get('/bar', (req, res) => {
    file2.fizz.buzz(req.field.item, res)   /*!!*/
    localfunction(param1, param2)
})

//file2.js
module.exports = {
  fizz: {
      buzz: (str, res) => {
          console.log("buzz")
      },
      bang: (param1, param2) => {
          console.log("bang!")
      }
  }
}

Thanks!

Im not sure what is your question. if you are asking about the /*! */ sign here is a good answer for it stackoverflow.com/a/11248430/9453736 — Mishel Parkour

An object? Or the word fizz itself? An object property (fizz being the property name, the object being the property value)? You might want to take a quick step back and spin through a JS tutorial real quick. — Dave Newton

module.exports = {} -> module.exports is an object; fizz: {} -> the property fizz on module.exports is also an object;` buzz: (str, res) => {...}` -> the property buzz on module.exports.fizz is a function. x = require('file2.js'); x.fizz.buzz() is how you access that function. — TKoL

Is there a name for wrapping multiple functions together like this in the fizz object? — jsarbour

The name for 'wrapping' multiple anything together in that format is simply called an object. You might also call it a 'map' — TKoL

fizz is a property name (on the object referenced by the file2 variable).
