'printf' vs. 'cout' in C++
...type safe". Most C implementations implement printf formats using computed goto, so the printf is as fast as it can be, even without compiler being aware of printf (not that they aren't - some compilers can optimize printf in certain cases - constant string ending with \n is usually optimized to put...
Java 8 Iterable.forEach() vs foreach loop
...ne less idiom. Heck, why use any loop, switch, or try/catch statement when goto can do all of that and more.

How using try catch for exception handling is best practice

poor programming method resembles the goto method in many software
languages but only occurs after a problem in the software is detected.

Why don't they teach these things in school? [closed]
...they are not? Why did the professor teach you program that way? To avoid gotos or to avoid constants or to avoid this and that? Is it because it produces more reliable code? Better performing code? Reduces human error? Or is it because it is easier to grade papers/programs giving them more tim...
What's the difference between a continuation and a callback?
...the full overhead of a function call. Instead it's implemented as a simple goto (with the stack frame of the calling function replaced by the stack frame of the tail call).
Bonus: Proceeding to continuation passing style. Consider the following program:
console.log(pythagoras(3, 4));
