const c = require('./c');

const doSomething = () => {
  c.doSomething();
};

module.exports = { doSomething };

// c.js

const stack = require('method-stack');
const doSomething = () => {
  console.log(stack.getCaller());
  /* Prints the caller, example:
  {
    file: 'C:\\Users\\User\\Documents\\Workspaces\\Lefcott\\npm\\method-stack\\b.js',
    method: 'doSomething',
    line: 6,
    col: 5
  }
  */
  console.log(stack.getCaller(1));
  /* Prints the caller of the caller, example:
  {
    file: 'C:\\Users\\User\\Documents\\Workspaces\\Lefcott\\npm\\method-stack\\a.js',
    method: '<anonymous>',
    line: 5,
