Lodash _.reverse

Overview

Description: The lodash _.reverse method is a powerful utility function that is used to reverse the order of the elements in an array. This method modifies the original array and returns the modified array with the reversed elements.

Syntax:

_.reverse(array)
  • array (Array): The array to modify.

Return Value: (Array): Returns the new reversed array.

Example:

const array = [1, 2, 3, 4, 5];
_.reverse(array);
// => [5, 4, 3, 2, 1]

const words = ['one', 'two', 'three'];
_.reverse(words);
// => ['three', 'two', 'one']

In the example above, we passed an array to the _.reverse() method, and it returned the new reversed array with its elements reversed. We can see that this has a few practical uses. For example, if we want to reverse the order of a list of elements displayed on a webpage.

There are a few things worth noting when using the _.reverse() method. First, as mentioned above, this method modifies the original array so it is important to keep that in mind. Second, this method is mutable, which means that it makes changes directly to the original array. This can be useful in some cases but can also cause unexpected problems in others. Lastly, this method returns a new array with the reversed elements - it does not modify the original array. Therefore, be sure to assign the returned value to a new variable if you want to keep the original array as it was.

In conclusion, the lodash _.reverse method is a handy utility function that has a few practical uses in web development. It is relatively simple to use and can be a useful tool for quickly reversing the order of elements in an array.
