Lodash _.forInRight


The lodash _.forInRight method is a powerful utility function for iterating over an object's properties, in reverse order. The method iterates over an object's own and inherited enumerable string keyed properties, invoking the callback function for each property.

The syntax for using _.forInRight is straightforward. The method takes two arguments: the object to iterate over, and the callback function to invoke for each property in reverse order. The callback function is invoked with three arguments: the value of the current property, the key or index of the current property, and the object being iterated over.

Here is an example of using _.forInRight to iterate over an object's properties in reverse order:

const _ = require('lodash');

const myObject = {
  name: 'John',
  age: 25,
  location: 'New York'

_.forInRight(myObject, (value, key) => {
  console.log(`${key}: ${value}`);

// Output:
// location: New York
// age: 25
// name: John

In the above example, the _.forInRight method is used to iterate over the myObject object's properties in reverse order. The callback function is invoked for each property, with the value and key of the property passed as arguments.

One important thing to note is that _.forInRight iterates over both the object's own properties and its inherited properties. If you only want to iterate over an object's own properties, you can use the _.forOwnRight method instead.

In summary, the lodash _.forInRight method is a powerful utility function for iterating over an object's properties in reverse order. With its simple syntax and ability to handle both own and inherited properties, it's a useful tool for many types of JavaScript applications.
