Not so long ago I started to code...
One of the main issues I had was to find short posts with simple examples, just to have a general idea of what I was trying to learn.
Knowing that my learning process is understanding the general idea of a concept and practising first, then diving deeper into it,I was often confronted with long and too complex posts. I'm not saying they weren't good, but they were too advanced for my level and made me raise too much questions instead of resolving the few I had - which usually were 'What is this concept ?', 'How does this concept works ?', 'How can I use it ?'.
This is why the posts 'A glance at...' will try to answer at these questions, with simple examples, hoping it will help some beginners :)
