✍️ Sample SASS Questions & Answers
1. What is the main purpose of the `@use 'sass:meta'` module?
The `sass:meta` module provides introspection functions like `meta.type-of()`, `meta.inspect()`, and `meta.load-css()` for examining Sass values and loading CSS dynamically.
2. What is the output of `percentage(0.5)` in Sass?
The `percentage()` function multiplies a unitless number by 100 and appends `%`, so 0.5 becomes 50%.
3. What does `@content` do inside a Sass mixin?
`@content` is a placeholder inside a mixin that is replaced by the block of styles provided at the `@include` site.
4. What does `meta.function-exists('function-name')` return?
`meta.function-exists()` returns a boolean indicating whether a function with the given name is defined and accessible in the current scope.
5. Which built-in module must you load with @use to access functions like map.get in modern Sass?
The sass:map module provides map functions such as map.get and map.set.
6. What is the difference between `@use` and `@forward` in Sass?
`@use` makes a module's members available in the current file, while `@forward` passes them through to files that import the current file.
