JavaScript happily supports four:</p> <ul> <li><strong>Imperative</strong> — describe the steps the computer takes (<code>for</code> loops, mutable state).</li> <li><strong>Procedural</strong> — group steps into named procedures (functions called for their side effects).</li> <li><strong>Object-oriented</strong> — bundle data with the methods that operate on it.</li> <li><strong>Functional</strong> — model computation as the evaluation of pure functions, prefer immutable data, and compose small functions into larger ones.</li> </ul> <p>JavaScript is sometimes called <em>multi-paradigm</em> because nothing in the language forces a single style. But its first-class functions, closures, and rich array methods make the functional style especially natural — and increasingly popular in front-end frameworks (React, Solid) and back-end ecosystems (RxJS, fp-ts).</p>
