Imperative vs Declarative Programming

imperative (how)

const h1 = document.createElement("h1")
h1.textContent = "Hello world"
h1.className = "header"
console.log(h1)

declarative (what)

// JSX
ReactDOM.render(<h1>This is JSX</h1>, document.getElementById("root"))

Generally, “declarative” programming is preferred, and they cause fewer bugs.
