The ‘work-count‘ module is a simple and lightweight external NPM module that can count the number of words in a string. This module provides a count() function, which counts the number of words by ignoring any special characters or symbols in the string.
Installation: First, we have to install the module using the command given below. Open the terminal, navigate to the same folder as your project, and then give the same command to install the module. After installation, a package.json file gets added to your project folder, which contains all the information regarding the installed modules.

Use the module: To use this module in the application, we have to incorporate the module into the project using the require keyword. Give the string to the module to process it and then show the output in the console of the terminal.
