What is replace() and replaceRecursive() methods in Collect.js?

Collect.js - Interview Questions

replace() : The replace() method behaves similarly to merge; however, in addition to overwriting matching items with string keys, the replace method will also overwrite items in the collection that have matching numeric keys:

const collection = collect({
  name: 'Bob',
});

const replaced = collection.replace({
  name: 'John',
  number: 45,
});

replaced.all();

// {
//   name: 'John',
//   number: 45,
// }

replaceRecursive() : This method works like replace, but it will recurse into arrays and apply the same replacement process to the inner values:

const collection = collect([
  'Matip',
  'van Dijk',
  [
    'Núñez',
    'Firmino',
    'Salah',
  ],
]);

const replaced = collection.replaceRecursive({
  0: 'Gomez',
  2: { 1: 'Origi' },
});

replaced.all();

// {
//   0: 'Gomez',
//   1: 'van Dijk',
//   2: { 0: 'Núñez', 1: 'Origi', 2: 'Salah' },
// }
