A closure-based implementation keeps the arguments collected so far private and returns another function until the original function's arity is satisfied.
<pre class="shiki github-dark shaku"><code>function curry(fn) { return function curried(...args) { if (args.length &gt;= fn.length) return fn(...args) return (...next) =&gt; curried(...args, ...next) }}</code></pre>
This supports both curry(fn)(a)(b) and curry(fn)(a, b) while preserving argument order.
