TypeScript Definitions: Define the `MMError` Type

[subhamkumarr]

Description:

In Wallet Create a React dapp with local state

• In step 6. Show connected wallet address. Currently, the TypeScript code references an MMError type, but it is not defined anywhere in the codebase. To improve type safety and developer experience, we should define the MMError type.

Steps to Reproduce

• Check the App.tsx file or any other file where MMError is referenced.
• Notice that the MMError type is used but not defined, leading to potential type errors or confusion.

Expected Behavior

The MMError type should be defined in a TypeScript definition file, providing clear structure and attributes that an MMError object should have.

Suggested Solution

Define the MMError type with appropriate properties. For example:

  code: number;
  message: string;
  [key: string]: any; 

This type definition should be placed in a relevant TypeScript definition file, such as types.ts, or in a global declaration file if applicable.

Additional Context

Including the MMError type definition will help improve code clarity and type safety, ensuring that all developers working on the project have a clear understanding of the structure and attributes of an MMError object.
