What is NPM

NPM stands for Node Package Manager and is the default JavaScript package manager powered by Node.js. The npm manager has two parts:

• CLI (Command Line Interface) — a tool for publishing and downloading packages,
• online repositories containing over 2 million JavaScript packages.

1. Create an npm project

• Create a folder named arraySort

mkdir arraySort

2. Initialize project as npm package

a) Using npm init -y or -yes

• This process will automatically generate a package.json file with default options.

npm init -y

b) Using npm init

• In this process, you will be asked a number of questions such as the name of the author, the description, and the license, etc.

npm init

3. Create a file named index.js with this content:

function arraySort(array, compareFunction) {
    const cloned = array.slice();
    if (compareFunction) {
        return cloned.sort(compareFunction);
    }

    return cloned.sort();
}

module.exports = arraySort;

4. Create a README.md (optional)

• You should provide a brief description of the repository and its functions.

5. Login into NPM

npm login

6. Publish the package

npm publish
