Sometimes, it is convenient to stop the loop repetition inside the loop when a certain condition is reached. This can be done with the break statement, which is as follows:
a = 10; b = 150 while a < b # process(a) println(a) global a += 1 if a >= 50 break end end
This prints out the numbers 10 to 49, and then exits the loop when break is encountered. The following is an idiom that is often used; how to search for a given element in an array, and stop when we have found it:
arr = rand(1:10, 10) println(arr) # get the index of search in an array arr: searched = 4 for (ix, curr) in enumerate(arr) if curr == searched println("The searched element $searched occurs on index $ix") break end end
