This is a quick introduction to the Managing Packes with NPM course on freeCodeCamp. We look at the structure of a node project, mainly the package.json file and node_modules folder and how to submit the challenges using Glitch.

It is the default package manager for the JavaScript runtime environment Node.js. It consists of a command line client, also called npm, and an online database of public and paid-for private packages, called the npm registry. https://www.npmjs.com/ package.json All npm packages contain a file, usually in the project root, called package.json - this file holds various metadata relevant to the project. This file is used to give information to npm that allows it to identify the project as well as handle the project's dependencies. It can also contain other metadata such as a project description, the version of the project in a particular distribution, license information, even configuration data - all of which can be vital to both npm and to the end users of the package. The package.json file is normally located at the root directory of a Node.js project. https://nodejs.org/en/knowledge/getting-started/npm/what-is-the-file-package-json/ node_modules Packages are dropped into the node_modules folder under the prefix. When installing locally, this means that you can require("packagename") to load its main module, or require("packagename/lib/path/to/sub/module") to load other modules. https://docs.npmjs.com/configuring-npm/folders.html#node-modules -————————————————————————————————————- The Node Package Manager (npm) is a command-line tool used by developers to share and control modules (or packages) of JavaScript code written for use with Node.js. freeCodeCamp (also referred to as “Free Code Camp”) is a non-profit organization that consists of an interactive learning web platform, an online community forum, chat rooms, online publications and local organizations that intend to make learning web development accessible to anyone.

There are many use cases where we need to check approximate equality. We can use Chai's approximately() method to do this. We provide an input (actual) value, a target (expected) value, and a variance (delta) to form the range around the target value which we can specify as approximately equal.

It makes testing much easier by giving you lots of assertions you can run against your code. freeCodeCamp (also referred to as “Free Code Camp”) is a non-profit organization that consists of an interactive learning web platform, an online community forum, chat rooms, online publications and local organizations that intend to make learning web development accessible to anyone. Beginning with tutorials that introduce students to HTML, CSS and JavaScript, students progress to project assignments that they complete either alone or in pairs. Upon completion of all project tasks, students are partnered with other nonprofits to build web applications, giving the students practical development experience.
