Validate JSON data against a schema using tools like `Ajv` (Another JSON Schema Validator). Define a JSON schema that specifies the structure and constraints of the data. Use the validator to check if the JSON data conforms to this schema. For example, create a schema with `const schema = { type: 'object', properties: { name: { type: 'string' } }, required: ['name'] };` and validate using `ajv.validate(schema, data)`.

useDeferredValue allows deferring updates to non-urgent state changes, making the UI more responsive. It works by deferring the rendering of less important updates, allowing more critical updates to be processed first, thus improving overall performance.

What is Angular's ChangeDetectionStrategy?

Angular's `ChangeDetectionStrategy` is a configuration that controls how Angular checks for changes in the application state and updates the view. There are two main strategies: `Default` and `OnPush`. The `Default` strategy checks all components in the component tree whenever an event or change occurs, ensuring that the view is updated accordingly. The `OnPush` strategy, on the other hand, limits change detection to components with changed input properties or events that originate from within the component. This can improve performance by reducing the frequency of change detection checks and is useful for optimizing large or complex applications.

The DATEDIF function calculates the difference between two dates based on a specified unit. For example, =DATEDIF(A1, B1, 'D') returns the number of days between the dates in A1 and B1. You can also use 'M' for months or 'Y' for years. This function is useful for calculating age, tenure, or duration.
