I’ve spent the last 10 years of my life as a System Engineer, which means when I first had to build an API, I had no idea how to do it. I knew python quite a bit since as a SysAdmin I often had to write some smaller or bigger scripts, but building the whole API was a challenge for me. Sure — I could just google the phrase and find dozens of tutorials on how to build an API, but all of them were somehow complicated or created for raw developers (which means — with assumptions that you know already all the tools and frameworks that developers use).

To learn coding is not just being familiar or comfortable with the syntax but to understand the logic and improve logical and analytical skills. Every programming language has advantages and disadvantages but the basics are the same to a certain extent. We all know that the best method to learn a programming language is writing codes in it. It is also known that the key developers not just write the code but enjoy doing it. If the basics are not sorted, advanced programming tends to be boring.

More than 500 languages are currently in use and a lot more are being written as we speak. The selection of a programming language is the first step to get into starting with the development cycle. A decade ago, developers were not bothered by the selection of technologies as they did not have access to an array of options.  The preference of a language is now based on the characteristics of a project and many such factors.

![](https://cdn.hackernoon.com/drafts/ttuiz32ti.png)
I am a huge fan of combat sports, with boxing in particular being my favourite. As much as it may appear as a purely physical sport where your sole objective is to either outbox or knock your opponent out, it is far more strategic that one would expect and incorporates an element psychology. Like a chess game, each punch thrown has to be calculated, recklessly overextending yourself might leave you more vulnerable to a counter punch, while being overly passive and defensive might swing the momentum in your opponent’s favour and not get you enough points to win the fight. If you let self-doubt sink in or are intimidated by your opponent you have already lost the battle. On top of all this, you need to remain respectful of the sport and the life threatening dangers it presents. In the words of of Sugar Ray Leonard, 'you don't play boxing'.

![](https://cdn.hackernoon.com/images/6WifzFKsrTU6u6nvz13jxc6dQ1O2-ge93qyi.jpeg)
Very often, some admins set limits on the speed of downloading files, this reduces the load on the network, but at the same time it is very annoying for users, especially when you need to download a large file (from 1 GB), and the speed fluctuates around 1 megabit per second (125 kilobytes per second). Based on these data, we conclude that the download speed will be at least 8192 seconds (2 hours 16 minutes 32 seconds). Although our bandwidth allows us to transfer up to 16 Mbps (2 MB per second) and it will take 512 seconds (8 minutes 32 seconds).

There are several thousand programming languages in the world. Even though many of them are incredibly unpopular, very specific, or have been created a long time ago, they still exist, and new languages continue to appear. It seems that there is no reason to believe that the number of languages will ever begin to decrease and that ultimately one universal programming language will emerge. The vast number of programming languages can frighten, but this very diversity allows us to move to a new level of multilingual project implementation. The article presents the idea of multilingual projects, which will enable developers not only to navigate in a variety of languages but also to see the benefits of their joint use.
