Eliminate redundant code

Simplify code by eliminating redundancy and unnecessary complexity. This improves readability, reduces potential bugs, and makes the codebase easier to maintain.

Some key practices to follow:

1. Avoid unnecessary object creation: Don’t create objects that might be discarded immediately. ```typescript // Instead of this: let requestOptions: RequestOptions | undefined = { …(config?.timeout ? { timeout: config.timeout } : {}), …(config?.signal ? { signal: config.signal } : {}), };

if (Object.keys(requestOptions).length === 0) { requestOptions = undefined; }

// Do this:

const requestOptions: RequestOptions | undefined = config?.timeout || config?.signal

? { timeout: config.timeout, signal: config.signal }

undefined; ```

1. Remove redundant await in returns: In async functions, avoid using await when returning a promise. ```typescript // Instead of this: async function getData() { return await fetchData(); }

// Do this: async function getData() { return fetchData(); }

3. **Use concise array methods**: Many array methods have default parameters you can omit.
```typescript
// Instead of this:
return embeddings.flat(1);

// Do this:
return embeddings.flat();

1. Don’t declare class properties only used in constructors: If a property is only accessed inside the class constructor, it doesn’t need to be a class property. ```typescript // Instead of this: class MyClass { json = false;

constructor() { if (this.json) { // do something } } }

// Do this: class MyClass { constructor() { const json = false; if (json) { // do something } } } ```

Eliminating redundancy leads to cleaner, more maintainable code that’s easier to review and less prone to errors.
