Lodash _.wrapperToIterator


The lodash _.wrapperToIterator method is a utility function that converts a wrapped value into an iterator object. It takes a single argument, which is the Wrapped object to convert. The returned iterator object can be used to iterate over the wrapped value. This method helps programmers who want to use a wrapped object within an iterator context.

The _.wrapperToIterator method is a part of the larger lodash library, which provides a wide variety of utility functions for working with arrays, objects, and functions in JavaScript. This library is widely used by web developers and is well-documented and maintained.

Using the _.wrapperToIterator method is simple. Here is an example:

const wrapped = _.chain([1, 2, 3])
  .map(n => n * 2)
  .filter(n => n > 3)

const iterator = _.wrapperToIterator(wrapped);

for (const item of iterator) {

In this example, we are using the _.chain method from lodash to create a wrapped array. We then use _.wrapperToIterator to convert this wrapped array into an iterator. Finally, we iterate over this iterator using a for...of loop and log each item to the console.

One important thing to note about _.wrapperToIterator is that it only works for lodash wrapped objects. It will not work for other types of iterators or iterable objects.

In conclusion, the _.wrapperToIterator method is an essential utility function for anyone using the lodash library. It provides a convenient way to convert lodash wrapped objects into iterators, thereby providing additional functionality and flexibility for developers.
