According to the data that I have collected (April, 2019), Jonatan Christie (21) has the biggest number of followers on Instagram among badminton players, most likely because the last year, 2018, he appeared to be the first Indonesian sportsman to claim Asian Games men’s singles gold title in the last 12 years.

What if…? Since Instagram and other social media are not accessible in China, its top athletes have to use local solutions.

Let’s say you need to display a number of different locations on a map.

I had a project where I had to import around 100 different files 30 times (from 30 folders), in order to do that, I used a function called fread from data.
