Control directives give you a way to add conditional logic to your Sass code. They allow you to branch your code in different directions based on different conditions and they allow you to loop through code until certain conditions are true or they stop being true.

Add Conditional Logic To Sass With Control Directives
One of the ways CSS can be limiting is the lack of conditional logic and loops. You’re limited in your ability to set a style if one condition is true or while another remains true. There are media queries which offer some conditional logic, but odds are you’ve wished you could test against more conditions than media queries allow.
Building Better Data Structures With Sass Maps
One downside of working with lists in Sass is you have to access values by an index you may not know. Maps solve that problem and allow you to access values based on key names you assign to them.
Manipulate And Retrieve Data With Sass List Functions
Lists are a series of values stored together as a data structure. On their own they’re not any more useful than regular Sass variables, however they become more useful when using the built-in functions Sass provides for working with them.
How To Store Data In Sass Lists
If you want to set a font-stack as a variable in Sass you could do something like $fonts: Helvetica, Arial, sans-serif in a single variable. Later you could assign the font stack with font-family: $fonts; However what if you only wanted to assign one of the fonts and not the whole stack? Sass lists might be your answer.
