## freeCodeCamp Curriculum
|
||||
|
||||
This directory contains code and data to "seed" the Mongo database with challenges.
|
||||
This package contains the "seed" files used in the freeCodeCamp Curriculum.
|
||||
|
||||
### Installation
|
||||
|
||||
```sh
|

||||
```
|
||||
|

### Usage
|
||||
|
||||
```js
|
||||
import { getChallenges } from '@freecodecamp/curriculum';
|
||||
|
||||
getChallenges() // will provide an array of blocks i.e. basic CSS, functional programming

"Debugging is frustrating, but it helps to develop (and follow) a step-by-step approach to review your code. This means checking the intermediate values and types of variables to see if they are what they should be. You can start with a simple process of elimination.<br><br>For example, if function A works and returns what it's supposed to, then function B may have the issue. Or start checking values in a block of code from the middle to try to cut the search space in half. A problem in one spot indicates a bug in the first half of the code. If not, it's likely in the second.<br><br>This section will cover a couple helpful tools to find bugs, and some of the common forms they take.

"Sass, or \"Syntactically Awesome StyleSheets\", is a language extension of CSS. It adds features that aren't available using basic CSS syntax. Sass makes it easier for developers to simplify and maintain the style sheets for their projects.<br><br>Sass can extend the CSS language because it is a preprocessor. It takes code written using Sass syntax, and converts it into basic CSS. This allows you to create variables, nest CSS rules into others, and import other Sass files, among other things. The result is more compact, easier to read code.<br><br>There are two syntaxes available for Sass. The first, known as SCSS (Sassy CSS) and used throughout these challenges, is an extension of the syntax of CSS. This means that every valid CSS stylesheet is a valid SCSS file with the same meaning. Files using this syntax have the .scss extension.<br><br>The second and older syntax, known as the indented syntax (or sometimes just \"Sass\"), uses indentation rather than brackets to indicate nesting of selectors, and newlines rather than semicolons to separate properties. Files using this syntax have the .sass extension.<br><br>This section introduces the basic features of Sass.",

Express runs between the server created by Node.js and the frontend pages of a web application. Express also handles an application's routing.

"MongoDB is a database that stores data records (documents) for use by an application. Mongo is a non-relational, \"NoSQL\" database. This means Mongo stores all data associated within one record, instead of storing it across many preset tables as in a SQL database. Some benefits of this storage model are:<br><br><ul><li>Scalability: by default, non-relational databases are split (or \"sharded\") across many systems instead of only one. This makes it easier to improve performance at a lower cost.</li><li>Flexibility: new datasets and properties can be added to a document without the need to make a new table for that data.</li><li>Replication: copies of the database run in parallel so if one goes down, one of the copies becomes the new primary data source.</li></ul><br>While there are many non-relational databases, Mongo's use of JSON as its document storage structure makes it a logical choice when learning backend JavaScript. Accessing documents and their properties is like accessing objects in JavaScript.<br><br>Mongoose.js is an npm module for Node.js that allows you to write objects for Mongo as you would in JavaScript.

Unlike encryptions, hashes cannot be transformed back into the original data. So how do you use a hash? A hash is used to verify data like a password again at a later point in time without actually knowing what it is in the future by hashing the entered password in the same manner as the original and comparing the results; if they match then you can be sure it is the same data. A widely used library for this is <em>BCrypt</em>.
