How to call a method from another class in JS?

Question

JavaScript

Good day. Faced one problem (not so selenium in JS) - I created 2 classes in two different files. In one of them, you need to call a method of another class. But no matter how I called (as I expected) - I can not call. He writes, they say:

(node:1240) UnhandledPromiseRejectionWarning: ReferenceError: ParserFile is not defined

Please tell me how to deal with this.

Actually code:

CLI.js

const ParseFile = require("./ParseFile");

class CLI {

  constructor() {
    (async () => {
      // Что то делает

      if (response.fileNew) {
        ParserFile.parseFile(response.fileNew);
      }

      if (response.fileOld) {
        ParserFile.parseFile(response.fileOld);
      }
    })();
  }
}

const cli = new CLI();

Cli.js main class. In the constructor, you need to call methods from the ParseFile.js class

ParseFile.js

export class ParserFile {
  parseFile(file) {
    // Что то выполняет
  }
}

const parserfile = new ParserFile();

Thanks in advance!

Read the documentation about static class methods (what you are currently calling), instantiation, and regular class methods.
Without documentation in any way, otherwise it's easier to pay someone.
