When you are writing a code, you have a very clear target: that the code will run and that the output will be accurate. But have you ever stopped and thought about the language in which you are writing in? The lecture will deal with topics that programmers usually don't talk about: calculation order, the variables environment, what happens behind the scenes, and in general - the meaning of every line of the code. This lecture is not just for experienced programmers but also for those who are new to programming and want to gain a deeper understanding of code.
