Design is the process of creating a plan or solution to a problem. It involves breaking down a complex system into smaller components and then finding ways to combine those components in order to achieve a desired outcome. In the context of JavaScript, design is about understanding how to structure code in order to create a robust, efficient, and maintainable application. Designing for JavaScript requires an understanding of the language’s syntax, data structures, algorithms, and other core concepts. Additionally, it involves making decisions about how to organize code, utilize libraries and frameworks, and structure the application architecture.
