How to use the tail function from underscore

underscore.tail is a function that returns a new array that excludes the first element of the original array.

How does underscore.tail work?

underscore.tail is a function that returns a new array that excludes the first element of the original array. When you call underscore.tail(), you pass in an array as a parameter. The function then creates a new array that consists of all the elements of the original array except for the first element. To create the new array, underscore.tail() uses the Array.prototype.slice() method to extract a subset of the original array. Specifically, it starts the subset from the second element (i.e., index 1) and includes all the remaining elements of the original array. The resulting subset of the original array becomes the new array returned by underscore.tail(). This function is useful for tasks that require working with arrays and need to exclude the first element of an array. For example, if you have an array of arguments and you want to exclude the first argument, you can use underscore.tail() to create a new array that contains all the remaining arguments. Overall, underscore.tail provides a simple way to create a new array that excludes the first element of an existing array, which can be useful for various array-related tasks in JavaScript.

const _ = require("underscore");

// Create an array of numbers
const numbers = [1, 2, 3, 4, 5];

// Get a new array that excludes the first element of the original array
const remainingNumbers = _.tail(numbers);

// Log the resulting array to the console
console.log(remainingNumbers);
// Output: [2, 3, 4, 5]

In this example, we use underscore.tail to exclude the first element of an array of numbers. We create an array of numbers using square brackets notation. We then pass the array to _.tail(), which returns a new array that consists of all the elements of the original array except for the first element. The resulting array contains all the remaining elements of the original array, which in this case are the numbers 2, 3, 4, and 5. We can use this array in various array-related tasks, such as filtering or mapping the remaining elements. Overall, underscore.tail provides a simple way to exclude the first element of an existing array and create a new array with the remaining elements, which can be useful for various array-related tasks in JavaScript.
