Q36: What is the difference between params and searchParams props in page components?
params: Contains dynamic route path segments defined in folder names (e.g.,/posts/[id]->{ id: '123' }).searchParams: Contains URL query string parameters (e.g.,/shop?category=shoes->{ category: 'shoes' }). In Next.js 15+, bothparamsandsearchParamsare asynchronous Promises.
Awaiting params and searchParams in Next.js 15+
// app/shop/[category]/page.js
export default async function Page({ params, searchParams }) {
const { category } = await params;
const { sort } = await searchParams;
return <div>Category: {category} | Sort By: {sort}</div>;
}💡 params and searchParams must be awaited prior to accessing properties in Next.js 15+.
