It was licensed under MIT license. It first appeared in the year 2006. After its initial development, SASS was extended to SassScript. It supports cross-platform operating systems. It was influenced by CSS, LESS, YAML etc. The types of file extensions for this SASS are .scss and .sass and its official implementation is also an open source project which was developed using Ruby.
SassScript also has different types of data types and also has different kinds of mechanisms such as nesting, variables, selector inheritance, and mixins.
Now, if you are looking for a job which is related to SASS then you need to prepare for the 2019 SASS Interview Questions.

Part 1 – SASS Interview Questions (Basic)
This first part covers basic SASS Interview Questions and Answers
1. What is SASS and what are its uses?
The SASS is useful in reducing the usage of CSS which will reduce the time and saves the code that in turn increases code reusability and reduces code redundancy. It provides own syntax for the CSS provides in developing more efficient code. SASS is a superset of CSS which is easier to use and it contains all the features of CSS.
2. How SASS is different from CSS?
This is the common SASS Interview Questions asked in an interview. CSS is Cascading Style Sheets whereas SASS is Syntactically Awesome Style Sheets and SASS is a superset of CSS and it contains all the features of CSS. SASS is a CSS pre-processor which will allow using the different operations and using variables, mixins, functions, imports and different kinds of loops. Any types of variables can be declared, defined and used. It will use nested syntax.
3. What is a variable and how is it defined in SASS?
A Variable in SASS is used to store the information which can be reused throughout the style sheet. A variable will be defined by starting it with a dollar ($) sign. To use the different types of colors, these variables will be useful to make them consistent across the application. Below are the examples for the definition of the variables. Here font is a variable which is started with a dollar sign and is defined as TimesNewRoman and the other variable is color which is also started with a dollar sign.

4. What are the different types of operations in SASS?
The different types of operations used in SASS are Number Operations List Operations String Operations Color Operations and Boolean Operations. Number Operations involves operations such as addition, subtraction, multiplication, and division. List Operations involves operations such as a set of values which are separated by commas in the form of an array. String Operations involve operations such as concatenation or splitting the strings. Color Operations involves operations such as using the Color components with arithmetic operations and finally, Boolean Operations involves operations such as using AND, OR, NOT operators to perform Boolean operations on SassScript.
5. What is Mixin?
A Mixin in SASS is a SASS Mixin which is called as CSS functions. Mixins can be used and included wherever they are needed in. A few functionalities in CSS which are difficult to implement can be done using Mixins. Values can also be passed to Mixins in case they are required. This will provide more reusability.
Part 2 – SASS Interview Questions (Advanced)
Let us now have a look at the advanced SASS Interview Questions.
6. What is SassScript and how it is different from SASS?
SassScript provides different types of mechanisms in CSS such as Nesting, Variables, Mixins, Selector Inheritance etc., SassScript is a set of small extensions which will be used by SASS. This can also be used with property names and selectors while being used with mixins.
7. What are different types of Mixin arguments?
The different types of Mixin arguments are Value Arguments and Keyword Arguments. The arguments can be SassScript values in the case of Mixins. These can be passed to Mixins and they will be available as variables in the Mixin and can be used within the scope of Mixin. Variable arguments are used to pass any number of arguments to Mixin. The keyword arguments passed to the Mixin can be accessed by using the Keywords.
8. What are different features available in SASS?
The different features in SASS are Reference Symbol, Partials and Directives, Interpolation, Placeholders, Functions, Lists etc. It will also super style the CSS by providing different functionalities to ease the development and provide code reusability. Variables, Nesting, and Math are also available in the SASS. The different CSS files can be easily combined by using an import directive. The different types of styles can be reused with Mixins. A mixin is a great feature where the code chunks will be reused easily without any code duplications. The styles can be extended with Inheritance.

9. What is Interpolation feature in SASS?
The Interpolation also called as Variable Substitution or Variable Interpolation which is defined as interpolating an expression or a variable. This is a process of a String or an expression containing more than one variable where these variables will be replaced in the memory with their corresponding values. Interpolation will have syntax to be used in the SASS.
10. What are the advantages and disadvantages of SASS?
SASS will allow writing clean CSS code and avoids code redundancy. SASS is a superset of CSS which will help the developers in writing the code more efficiently and quickly. SASS is also compatible with different kinds of CSS versions and any available CSS libraries can be used. It has a powerful syntax which will help in writing the short and efficient code. The disadvantages of CSS are that it will have more learning curve for the developers to learn all the features involved in SASS. The number of developers using the same scripts will have an impact if one has modified for their requirement and will impact this in the case of development.
