How does ramda.dropLast work?

ramda.dropLast is a utility function provided by the Ramda library that takes an array or string and a number n as input, and returns a new array or string with the last n elements or characters removed.

When ramda.dropLast is called, it creates a new array or string by copying all of the elements or characters from the input, except for the last n elements or characters.

If the input has fewer than n elements or characters, ramda.dropLast will return an empty array or string.

ramda.dropLast does not modify the input array or string; instead, it returns a new array or string that represents a modified version of the input.

By providing a functional and flexible way to drop elements or characters from the end of an array or string, ramda.dropLast can be used in a wide range of applications, such as data processing, text manipulation, and user interface development.

const R = require("ramda");

// Output: [1, 2]

In this example, we import the ramda library and create an array arr with five elements. We then use R.dropLast to create a new array result with the last three elements of arr dropped. The resulting array has only the first two elements of the original array: [1, 2]. Similarly, ramda.dropLast can be used to remove characters from the end of a string: javascript Copy code
