In [[computer science]], '''imperative programming''' is a [[programming paradigm]] of [[software]] that uses [[Statement (computer science)|statement]]s that change a program's [[state (computer science)|state]]. In much the same way that the [[imperative mood]] in [[natural language| (natural) languages]]s is used, for instance, to express commands, an imperative program consists of [[command (computing)|command]]s for the [[computer]] to perform. Imperative programming focuses on describing ''how'' a program operates step by step,<ref>{{Cite web |last=Jain |first=Anisha |date=2022-12-10 |title=Javascript Promises— Is There a Better Approach? |url=https://medium.datadriveninvestor.com/javascript-promises-is-there-a-better-approach-dd6a0a329131 |access-date=2022-12-20 |website=Medium |language=en}}</ref> rather than on high-level descriptions of its expected results.

The term is often used in contrast to [[declarative programming]], which focuses on ''what'' the program should accomplish without specifying all the details of ''how'' the program should achieve the result.<ref>{{Cite web |title=Imperative programming: Overview of the oldest programming paradigm |url=https://www.ionos.com/digitalguide/websites/web-development/imperative-programming/ |access-date=2022-05-03 |website=IONOS Digitalguide |date=21 May 2021 |language=en}}</ref>
