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
A possible output might ...
