Define ‘createdAt’, ‘updatedAt’ type in interface in typescript

In TypeScript, you can define createdAt and updatedAt fields in an interface to represent timestamps using either the Date type or a custom type. Here’s how you can define them using the Date type:

interface MyInterface {
    // Other fields...
    createdAt: Date;
    updatedAt: Date;
}

This approach uses the built-in Date object provided by JavaScript. Alternatively, if you want to use a custom type for timestamps, you can define it like this:

type Timestamp = number;

interface MyInterface {
    // Other fields...
    createdAt: Timestamp;
    updatedAt: Timestamp;
}

In this example, we define a Timestamp type as a number, which represents the number of milliseconds since the Unix epoch. You can customize this type according to your requirements, such as using a string type to represent ISO 8601 formatted timestamps.

Choose the approach that best fits your use case and coding style. Both approaches are valid, and the choice depends on your specific needs and preferences.

I always remember that typescript help us with many things which why pushing and trying more eventually helps. Typescript provide us many advantages such as Static Typing, TypeScript introduces static typing to JavaScript, allowing developers to define explicit types for variables, parameters, and return values. This helps catch type-related errors during development, leading to fewer runtime errors and improved code reliability. Enhanced Code Readability, With type annotations, TypeScript code becomes more self-documenting, making it easier for developers to understand the purpose and expected usage of functions, classes, and variables. This can improve code maintainability, especially in large codebases with multiple contributors.
