Global and Scoped variables

It should be noted that in Sass 3.4.21 (Selective Steve), this scoping works like JavaScript, exactly as the deprecation warning shown in the terminal in this video.

This :

$text-color : blue;

h1 { $text-color: red; 
    color: $text-color;

}

h2 { color: $text-color; }

compiles to this:

h1 { color: red; }

h2 { color: blue; }

so $text-color remains in the global scope where it was first defined

The reason you would want to do that is because if you want to use that same color in other places in your code you wouldnt have to memorize the hex value you would just use $whichever-color everytime. plus if you work in a team its easier as well. Sass is really useful you should look in to mixins as well you can put a bunch of values in one mixin and then implement it in to your code. For example:

@mixin text-style {

      color: red;
      font-size: 16px;
      background-color: blue;

}


/* use in css */

P {

     @include text-style;

}

Now you dont have to worry about memorizing or copy pasting pieces of code you already wrote. Let me know if that helped you. :)

The purpose of that was purely as an example of how variables scope in Sass. This would not be used in real projects.
