//expected result {ab: {cd: {e:'foo', f:'bar'}, g:'foo2'}}

function deepen(obj) {
  const result = {};

  // For each object path (property key) in the object
  for (const objectPath in obj) {
    // Split path into component parts
    const parts = objectPath.split('.');

    // Create sub-objects along path as needed
    let target = result;
    while (parts.length > 1) {
      const part = parts.shift();
      target = target[part] = target[part] || {};
    }

    // Set value at end of path
    target[parts[0]] = obj[objectPath]
  }

  return result;
}

// For example ...
console.log(deepen({
  'ab.cd.e': 'foo',
  'ab.cd.f': 'bar',
  'ab.g': 'foo2'
}));

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
