Static Site Generation (SSG) in Next.js generates HTML at build time, resulting in fast, static pages. Server-Side Rendering (SSR) generates HTML on each request, providing up-to-date content. SSG is ideal for content that doesn't change frequently, while SSR is better for dynamic content that needs to reflect real-time data.

The `<meta>` tag in HTML provides metadata about the document, such as character set, viewport settings, and SEO information. Common attributes include `charset`, `name`, `content`, and `http-equiv`. Meta tags play a crucial role in optimizing a web page for search engines and ensuring proper rendering across different devices.

Static Site Generation (SSG) in Next.js involves pre-rendering pages at build time, generating static HTML files for each page. This improves performance and SEO by serving pre-built pages. To implement SSG, you can use the `getStaticProps` and `getStaticPaths` functions. SSG is suitable for content that doesn't change frequently, such as blogs and documentation.

`String.prototype.toUpperCase` returns a new string with all characters converted to uppercase. 

const str = 'hello';
const upper = str.toUpperCase();
console.log(upper); // 'HELLO'

`String.prototype.toLowerCase` returns a new string with all characters converted to lowercase. 

const str = 'HELLO';
const lower = str.toLowerCase();
console.log(lower); // 'hello'

useImperativeHandle allows customizing the instance value exposed to parent components when using refs. Benefits include fine-grained control over exposed methods, while drawbacks include potential overuse leading to less predictable code and harder-to-maintain components.

Redux Thunk is a middleware that allows action creators to return a function instead of an action object. This enables handling asynchronous operations. For example, you can fetch data from an API and dispatch an action once the data is received.

API routes in Next.js are serverless functions used to create back-end APIs directly in the application. You can handle different requests like GET or POST inside `pages/api`. Example: A simple API route at `pages/api/hello.js` can return a JSON response with a message: `{ 'message': 'Hello' }`.
