Difference in Installation Method

Which statement correctly describes the installation difference between Dart SASS and Node SASS?

A Dart SASS is installed as a standalone executable or via npm, while Node SASS requires native bindings and compilation.

B Node SASS requires a native binding compilation during installation, while Dart SASS is a pure JavaScript implementation.

C Dart SASS is installed via npm and runs on Node.js, while Node SASS is a standalone binary.

D Both Dart SASS and Node SASS are installed only as standalone executables and do not use npm.

💡 Hint

Think about how native bindings affect installation complexity.

Dart SASS can be installed as a standalone executable or via npm and does not require native bindings. Node SASS requires native bindings and compilation during installation, which can cause issues on some systems.

📝 Syntax

Syntax Compatibility

Which Sass syntax feature is supported by Dart SASS but not fully by Node SASS?

A The @import rule for legacy Sass files.

B Variables declared with $ symbol.

C Nesting selectors inside media queries.

D The @use rule for modular Sass code.

💡 Hint

One syntax is newer and recommended for modular code.

Dart SASS fully supports the modern @use rule for modular Sass code, while Node SASS has limited or no support for it. Both support @import, nesting, and variables.

Output Differences in Compilation

Given the same Sass file using the @use rule, what will happen if compiled with Node SASS?

SASS

@use 'colors';

body {
  color: colors.$primary;
}

A Compilation succeeds and outputs CSS with the primary color.

B Compilation fails with an error about unknown @use rule.

C Compilation succeeds but ignores the @use rule and outputs empty CSS.

D Compilation succeeds but outputs a warning and CSS with default color.

💡 Hint

Node SASS does not support the @use rule.

Node SASS does not support the @use rule and will throw a compilation error when encountering it.

❓ selector

Selector Nesting Behavior

Which statement about selector nesting support is true comparing Dart SASS and Node SASS?

A Only Dart SASS supports the new parent selector nesting with & inside media queries.

B Both Dart SASS and Node SASS support the new parent selector nesting with &.

C Node SASS supports all nesting features including the new & syntax inside media queries.

D Neither Dart SASS nor Node SASS support nesting selectors inside media queries.

💡 Hint

Consider which implementation is more up-to-date with Sass specs.

Dart SASS supports the latest nesting features including using the parent selector & inside media queries. Node SASS lacks support for some of these newer features.

Accessibility and Sass Compilation Speed Impact

How does the choice between Dart SASS and Node SASS affect accessibility-focused development workflows?

A Node SASS includes built-in accessibility linting tools, unlike Dart SASS.

B Node SASS compiles faster, enabling more frequent accessibility audits during development.

C Dart SASS's faster compilation allows quicker testing of accessible styles, improving workflow efficiency.

D Both have identical compilation speeds, so accessibility workflows are unaffected by the choice.

💡 Hint

Think about how speed affects testing cycles.

Dart SASS generally compiles faster than Node SASS, which helps developers quickly test and iterate on accessible styles, improving the development workflow.
