There are other options other than what you are asking for that provide similar functionality. For example: You can avoid processing some values using filter: (like a continue) dataSet.filter { it % 2 == 0 }.forEach { // do work on even numbers } You can stop a functional loop by using takeWhile: (like a … Read more
UPDATE: This question was inspiration for my article on this subject. Thanks for the great question! “continue” and “break” are nothing more than a pleasant syntax for a “goto”. Apparently by giving them cute names and restricting their usages to particular control structures, they no longer draw the ire of the “all gotos are all … Read more
Yes, they do completely different things. pass simply does nothing, while continue goes on with the next loop iteration. In your example, the difference would become apparent if you added another statement after the if: After executing pass, this further statement would be executed. After continue, it wouldn’t. >>> a = [0, 1, 2] >>> … Read more
It’s fine, the continue statement relates to the enclosing loop, and your code should be equivalent to (avoiding such jump statements): while (something = get_something()) { if (something == A || something == B) do_something(); } But if you expect break to exit the loop, as your comment suggest (it always tries again with another … Read more
Here’s a simple example: for letter in ‘Django’: if letter == ‘D’: continue print(“Current Letter: ” + letter) Output will be: Current Letter: j Current Letter: a Current Letter: n Current Letter: g Current Letter: o It skips the rest of the current iteration (here: print) and continues to the next iteration of the loop.
break leaves a loop, continue jumps to the next iteration.
continue is kind of like goto. Are you familiar with break? It’s easier to think about them in contrast: break terminates the loop (jumps to the code below it). continue terminates the rest of the processing of the code within the loop for the current iteration, but continues the loop.

Yes, it’s called next. for i in 0..5 if i < 2 next end puts “Value of local variable is #{i}” end This outputs the following: Value of local variable is 2 Value of local variable is 3 Value of local variable is 4 Value of local variable is 5 => 0..5
