What are the differences between Sass, Less, and Stylus?

What are the differences between Sass, Less, and Stylus?

Sass, Less, and Stylus are all CSS preprocessors that enhance CSS with features like variables, nesting, and mixins. Sass is known for its powerful features and is widely used, while Less is simpler and integrates well with JavaScript. Stylus offers a more flexible syntax and is highly customizable.

Which one should I choose for my project?

It depends on your project needs. If you want a robust feature set, go for Sass. If you prefer simplicity and JavaScript integration, choose Less. For flexibility and customization, Stylus is a great option.

Can you give me an example of how to use variables in each?

Sure! In Sass, you define a variable like this: $primary-color: blue;. In Less, it's @primary-color: blue;, and in Stylus, you can use primaryColor = blue. Each has its own syntax but serves the same purpose.

Are there any performance differences between them?

Generally, the performance differences are minimal and often depend more on how you structure your code rather than the preprocessor itself. However, Sass is often considered slightly slower due to its extensive feature set.
