Why your software should use UUIDs in 2020s

https://devforth.io/blog/why-your-software-should-use-uuids-in-2020s

Excerpt:

Conclusion

• UUIDs solve the problem of centralized ID store making possible working in offline and handle complex relations on frontend by making frontend independent from the server which makes it super-responsive
• UUIDs allow you to implement shards for high-load scalable systems
• UUIDs make your IDs more secure by hiding records count
• To decrease insert time use UUIDv1 as IDs system
• Store it in the database as 16 bytes
• To save traffic transmit Shot UUIDs

Iterator

Excerpt from https://davidwalsh.name/es6-generators

Iterators are a special kind of behavior, a design pattern actually, where we step through an ordered set of values one at a time by calling next(). Imagine for example using an iterator on an array that has five values in it: [1,2,3,4,5]. The first next() call would return 1, the second next() call would return 2, and so on. After all values had been returned, next() would return null or false or otherwise signal to you that you've iterated over all the values in the data container.

Difference between Dynamic Programming & Divide And Conquer

https://en.wikipedia.org/wiki/Dynamic_programming

There are two key attributes that a problem must have in order for dynamic programming to be applicable: optimal substructure and overlapping sub-problems. If a problem can be solved by combining optimal solutions to non-overlapping sub-problems, the strategy is called "divide and conquer" instead.^[1] This is why merge sort and quick sort are not classified as dynamic programming problems.
