Lodash _.takeRight


The lodash _.takeRight method is a widely-used utility function in JavaScript development. It is a part of the popular lodash library, which provides a wide range of utility methods for working with arrays, objects, and collections in JavaScript.

The _.takeRight method is used to create a new array with the specified number of elements taken from the end of an existing array. The original array is not modified by this method. It accepts two arguments: the array and the number of elements to take from the end of the array.

Here is the basic syntax:

_.takeRight(array, [n=1])
  • array (Array): The array from which to take elements.
  • [n=1] (number): The number of elements to take.

The _.takeRight method returns a new array containing the last n elements of the input array.

Here are some examples of using _.takeRight:

const array = [1, 2, 3, 4, 5];

_.takeRight(array); // [5]
_.takeRight(array, 2); // [4, 5]
_.takeRight(array, 3); // [3, 4, 5]
_.takeRight(array, 6); // [1, 2, 3, 4, 5]

If the input array is empty, the method returns an empty array. If n is greater than the length of the input array, the method returns a new array with all of the elements in the original array.

Overall, the _.takeRight method is a simple and powerful utility function that can be useful in a wide range of JavaScript applications.
