lodash.forown

What is lodash.forown?

The lodash.forown package is a utility function from the Lodash library that iterates over own enumerable string keyed properties of an object and invokes a function for each property. This is useful for object manipulation and iteration tasks.

What are lodash.forown's main functionalities?

Iterate over object properties

This feature allows you to iterate over the own enumerable string keyed properties of an object. The provided function is invoked for each property, receiving the value and key as arguments.

const _ = require('lodash.forown');
const object = { 'a': 1, 'b': 2, 'c': 3 };
_.forOwn(object, function(value, key) {
  console.log(key, value);
});

Early exit from iteration

This feature allows you to exit the iteration early by returning `false` from the iteratee function. This can be useful when you need to stop processing once a certain condition is met.

const _ = require('lodash.forown');
const object = { 'a': 1, 'b': 2, 'c': 3 };
_.forOwn(object, function(value, key) {
  if (key === 'b') {
    return false;
  }
  console.log(key, value);
});

object-foreach

The object-foreach package provides similar functionality to lodash.forown by iterating over the own properties of an object. It is a lightweight alternative but lacks the extensive utility functions provided by Lodash.
