DeclarativeProgramming

Adopting declarative-style programming techniques allows teams to create web applications that are easier to extend and maintain.

In this article, Toptal Full-stack Developer Peter Suggate demonstrates how to leverage declarative programming and finite-state machines in JavaScript.

In a nutshell, declarative programming consists of instructing a program on what needs to be done, instead of telling it how to do it. This approach involves providing a domain-specific language (DSL) for expressing what the user wants. This DSL shields users from messy low-level constructs while still achieving the desired end-state.

While declarative programming offers advantages over the imperative approach it replaces, it’s not as straightforward as it may seem. In this comprehensive article, Toptal Freelance Software Engineer Federico Pereiro outlines his experience with declarative tools and explains how you can make declarative programming work for you.
