isSymmetrical(44444444) ➞ true
isSymmetrical(9939) ➞ false

The spacer is the third argument to JSON.stringify.

You can pass a String or a Number that is used to insert white space into the output.

If you pass a String, it will use it as the “space” character.

Designing Data-Intensive Applications

Amazon: 4.8 / Goodreads: 4.7

Data is at the center of many challenges in system design today. Difficult issues need to be figured out, such as scalability, consistency, reliability, efficiency, and maintainability. In addition, we have an overwhelming variety of tools, including relational databases, NoSQL datastores, stream or batch processors, and message brokers. What are the right choices for your application? How do you make sense of all these buzzwords?

In this practical and comprehensive guide, author Martin Kleppmann helps you navigate this diverse landscape by examining the pros and cons of various technologies for processing and storing data.

Software keeps changing, but the fundamental principles remain the same. With this book, software engineers and architects will learn how to apply those ideas in practice, and how to make full use of data in modern applications.

You can use an empty 'placeholder' comma to skip elements when destructuring arrays.

If you want to access the second or third element from a list, or want to skip the first or second element (etc), this is a great and clean way to do it.

2021-10-01 00:58:00 ​​ Prototyping is a learning experience

Its value lies not in the code produced, but in the lessons learned.

You can prototype anything that carries risk, unproven, is absolutely critical to the final system. It can be:

Architecture

New functionality in an existing system

External data structure

Third-party tools or components

Performance issues

User interface design

When building prototypes you should focus on specific aspects. These are the details you can ignore:

Correctness - use dummy data where appropriate

Completeness - isolate the concept you're proving

Robustness - be specific, error checking may be excessive

Style - after all, you're going to throw the prototype away anyway

Properly used prototypes can save you huge amounts of time, money, and pain by identifying potential problems early in the development cycle - the time when fixing mistakes is both cheap and easy.
