Setting up the JSON files

Each Harp project has at least two JSON files that are used for configuring a project. JSON stands for JavaScript Object Notation and it's a lightweight format for data interchange. If that sounds complicated, don't worry about it. The actual coding of a JSON file is actually really straightforward, as I will show you now.

The first is called _harp.json and it's used for configuring global settings and variables that will be used across the entire blog. In this case, we're going to set up a global variable for the name of our project that will be inserted into every page template. Start by creating a new file in the root of blog project and call it _harp.json. Within the file, insert the following code:

{ 
   "globals": { 
      "siteTitle": "Learning Bootstrap 4" 
   } 
} 

Here's what's happening in this code:

• We're using the globals keyword so any variables under this will be available across all of our templates

• I've created a new variable...
