React Hook for Add/Switch Chain to any Ethereum Network in MetaMask

When Switching or Adding and then Switching to another Network/Chain within a dapp like React using MetaMask API. You can build a React Hook with the concept in this GitHub Gist included below.

The code between lines 36 and 68 could be used outside of a React Hook in the case you just want to know how to create a single JavaScript/TypeScript function for adding/switching Ethereum chain.
