Call multiple nested functions in the same file that is not a functional or class component?

How I call other other functions from a helper file that isn’t a component?
I have multiple components using the same 3 functions but the 3 functions are all dependent on a dom event/event listener and requires the “this” to be passed down to other functions.

Do I need to create a functional component to hold these additional functions? What is the correct to call them?

NewItem.js

import React, { Component } from 'react'
import {funcA} from 'SomeHelper'
class NewItem extends Component {
  constructor(props) {
    super(props);
  }

  render() {
    return(
      <div>{funcA(userName, obj)}</div>
    )
  }
}

SomeHelper.js

export const funcA(userName, obj) => {
    return console.log( funcB(userName, obj), funcCalculate(obj) )
}

funcB(userName, obj) => {
  return "Hello World" + userName;
}

funcCalculate(obj) {
  let value = 1 + 1;
  //insert some code here.
  return value;
}
