When your application grows and traffic increases, your servers eventually struggle.
So what should you do next?
In this video, we explain:
- What scaling really means
- Vertical Scaling (Scaling Up)
- Horizontal Scaling (Scaling Out)
- Advantages and disadvantages of both approaches
- When to use vertical scaling vs horizontal scaling
- Real-world system design intuition
This video is perfect for:
- Computer Science students
- Backend developers
- System design beginners
- Interview and exam preparation
Explained simply, visually, and step by step.

🚨 Did you know there's a new way to copy objects in JavaScript?
🔍 Say goodbye to messy code and hello to `structuredClone` - the native function that lets you make deep copies of objects, even those with nested objects and arrays.
🤯 No more worrying about updates to the original object, or using those other methods that don't support certain types.
💪The function makes it easy to copy an object without affecting the original.
Please note that `structuredClone` is available in Node.js v17 and above, and supported by all major browsers.🌐
Hey there, fellow programmers! I've finally decided to grace LinkedIn with my presence.
That's right, `Sayef Reyadh - Programming Made Simple` is now on LinkedIn! If you're a fan of casual tutorial videos on various computer science topics, or just enjoy a good programming joke, then come join me. We'll learn new things, make terrible puns, and hopefully not break the internet in the process. See you there!

Did you know that TypeScript has a set of built-in utility types that can help you write more robust and maintainable code? 🤔
These types, known as "utility types", provide a set of common operations on types, such as mapping, filtering, and picking properties. Here are some of the built-in utility types provided by TypeScript. 😍
- Partial: Makes all properties of a type optional.
- Required: Makes all properties of a type required.
- Pick: Picks a set of properties from a type.
- Omit: Omit certain properties from a type.
- Record: Creates a type with a set of properties of a certain type.
This is not a complete list of all the utility types in TypeScript, but it includes some of the most common ones I use on a regular basis. Keep in mind that these utility types are a part of the TypeScript language and not a library, so you don't need to install any additional packages to use them. 🤥
Give them a try and see how they can improve your TypeScript development! 😉

Refactoring core utility methods is usually difficult and may result in unanticipated bugs in the system. Especially if you're part of a large team and don't want another member's feature branch to be delayed.
Instead of refactoring the core method all at once, we may create a wrapper method/v2 method that performs the new functionality while marking the original method as deprecated using a docstring. In this way, the team can use the old method and also will be able to migrate and refactor to the new method, with necessary changes, knowing that the old one will be deprecated.
