How to use the words function from underscore.string

underscore.string.words is a JavaScript function in the Underscore.string library that splits a string into an array of words, with customizable delimiters and filters.

How does underscore.string.words work?

underscore.string.words works by splitting a string into an array of words, with customizable delimiters and filters. When called with a string as its argument, underscore.string.words splits the string into an array of words, using whitespace as the default delimiter. The resulting array contains each word in the string, in the order they appear, with any leading or trailing whitespace removed. The delimiter used to split the string can be customized using the delimiter argument, which can be a regular expression, a string, or a function that returns a regular expression or string. The delimiter can also be omitted, in which case the default whitespace delimiter is used. The resulting array of words can be further filtered or processed using the filter argument, which can be a regular expression, a string, or a function that returns a Boolean value. The filter can be used to exclude or include specific words in the array, based on their content or length. The resulting array of words can also be mapped or reduced using other Underscore.js or Underscore.string functions, such as _.map, _.reduce, or _.pluck. Note that underscore.string.words is part of the Underscore.string library, which extends the functionality of the Underscore.js library with various string manipulation and formatting functions, and provides a more convenient and readable API for working with strings in JavaScript.

const _ = require("underscore");
require("underscore.string");

const str = "The quick brown fox jumps over the lazy dog";

const words = _.words(str);

console.log(words);
// Output: ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"]

In this example, we first import the Underscore.js and Underscore.string libraries, and define a string str containing a sentence with several words. We then call the _.words function with str as its argument, which splits the string into an array of words using the default whitespace delimiter. The resulting array of words is then printed to the console. The output will be an array containing the words in the original sentence, in the order they appear, with any leading or trailing whitespace removed. Note that this is just a simple example, and underscore.string.words can be used to split strings with various delimiters and filters, and can be combined with other Underscore.js or Underscore.string functions to perform more complex string manipulations or transformations.
