The times iterator will take a number and execute the statements in the block that number of times. The times iterator optionally takes an argument and, just like array indices, starts at 0.
Code Samples
Using a number, we can iterate that amount of times:
5.times do
puts "Hello!"
end
This will print "Hello!" to the screen 5 times.
The times method also can take a single argument:
5.times do |item|
puts "Hello! #{item}"
end
Just like an array index, the times index starts at 0.
Another kind of iterator in Ruby that works specifically with 0:00 integers is the times iterator. 0:04 The times iterator will take a number, 0:07 execute the statements in the block that number of times. 0:10 The times iterator, optionally, 0:14 takes an argument, and, just like array indexes, starts at zero. 0:16 Let's see how that works now using WorkSpaces. 0:22 Okay, using a Ruby workspace let's go ahead and create a new file. 0:25 We'll call this times.rb. 0:29 The times method is really easy to use. 0:31 We'll take any number, let's use 5 as an example and 0:36 use a dot like we're going to call a method and then we use the word times. 0:40 From there, we write a do end block like we're used to. 0:48 Now let's just type puts hello. 0:52 Now we can run this, using ruby times.rb. 0:57 And we see that it prints hello five times. 1:02 And we can also send arguments into the times method. 1:10 Let's create a new file. 1:16 To test that out, we'll call it times with argument.rb. 1:18 And we'll write that just like we did the times loop. 1:24 So here we did five times. 1:29 Do end. 1:34 Now just like with other iterators and blocks, 1:37 if we want to send an argument to the block we do so by writing a pipe and 1:40 putting the local variable inside of the pipes. 1:45 The times method can take one argument into the block 1:50 and we'll go ahead and print that out. 1:56 And if we run ruby times_with_argument.rb. 2:02 We can see, we get all of these different arguments as the item and 2:06 it starts with zero just like array indexes. 2:11 Try practicing with the times iterator on your own now, using WorkSpaces. 2:16
