What data structure would you use to determine whether an entity is in a given dataset with speed? Many would answer “Hashtable” without hesitation. Hashtable performs well when accessing an entity among a group of entities: the average time complexity of its read operations is constant. Nevertheless, using Hashtables can be rather costly when dealing with large datasets....Deciding to Grow
Moving to Japan The first time I came to Japan, I was a tourist. I spent 1 week here during my final year of college.

For many software engineers, endpoints for retrieving a list of entities are probably their favorite to implement–all they need to do is build an SQL statement that grabs all the available items, along with some other minor tasks.

Recently, I joined a new project at Colorkrew that uses Golang as its backend language. Almost everyone on the team, including myself, had no experience with Golang, so we had to start from zero.

After all, it is one of the most in demand programming languages now....Separation of Concerns: Split Your React Components into Containers and Views
Many frontend engineers probably have experienced the head-scratching moment when their React components become so gigantic that they keep losing their train of thought when navigating through their frontend code.

To explain why it’s so important to me personally, it helps to establish a few things about my background…...RESTful API 101
It is almost impossible for a backend engineer to be oblivious to RESTful API in the 21st century, as it is one of the most popular API types. We can mostly attribute its popularity to its scalability, flexibility, and simplicity, all of which are highly sought-after qualities in modern APIs. If you also find these qualities desirable, you should consider building APIs following the RESTful principles....
