React concepts: declarative

New Course Coming Soon:

Get Really Good at Git

What does it mean when you read that React is declarative

You’ll run across articles describing React as a declarative approach to building UIs.

React made its “declarative approach” quite popular and upfront so it permeated the frontend world along with React.

It’s really not a new concept, but React took building UIs a lot more declaratively than with HTML templates:

The opposite of declarative is imperative. A common example of an imperative approach is looking up elements in the DOM using jQuery or DOM events. You tell the browser exactly what to do, instead of telling it what you need.

The React declarative approach abstracts that for us. We just tell React we want a component to be rendered in a specific way, and we never have to interact with the DOM to reference it later.

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching May 21, 2024. Join the waiting list!
