Types v/s Interfaces in TypeScript - A Dilemma

Jit Mitra — Wed, 11 Sep 2024 17:34:41 +0000

When venturing into TypeScript, many encounter the dilemma of whether to employ Types or Interfaces, as both appear to fulfill the same function: predefining data or object types for future use.

The TypeScript official documentation recommends prioritizing Interfaces over Types. This preference stems from Interfaces offering clearer error messages and the ability to extend them by re-declaring, a capability not shared by Type aliases. However, it's imperative to delve deeper into their respective use cases for a comprehensive understanding. The link to the referenced article can be located in the Further Reading section.

While I endorse this recommendation, it's essential to discern specific scenarios where each option shines. Generally, opting for Interfaces over Type aliases remains prudent due to the advantages outlined earlier. However, one exception exists: when aiming to create a type that should remain immutable, with no possibility of external additions.

For instance, suppose you wish to define a custom user type comprising only username, password, and email fields—no more, no less. In such a scenario, leveraging Type aliases ensures the intended purpose remains intact, safeguarding against inadvertent modifications by others.

Attention: If you’re here to learn about DBMS, feel free to skip the prologue—it's intended for a general audience :)

Hello everyone! This article kicks off a series on Database Management Systems (DBMS). These articles are not your typical online fare; instead, they focus on core concepts rather than just textbook definitions. My goal is not merely to help you ace an interview, but to provide a deep, comprehensive understanding of the subject based on my knowledge and expertise. While mastering the material will certainly benefit your interview performance, please note that this is not a crash course. Don’t expect frequent updates - each article will take time to ensure the highest quality. I’ve also included practical insights to enhance your learning experience.

Let's begin with a common question that arises when learning about DBMS: What’s the difference between a database and a database management system? The distinction is somewhat clear from the names themselves, but let's delve into it in more detail.

What is a Database?

A database is an organized collection of interrelated data stored electronically within a computer system.

What is a Database Management System (DBMS)?

A Database Management System (DBMS) is software designed to manage and interact with databases. It provides a user interface for performing various operations with the database.

What do we mean by "interaction"?
Interaction refers to operations such as creating databases, storing data, updating the stored data, and deleting information, among other tasks.

That’s all for this article. See you in the next one!
