Iterate the number of times of integers value Crystal

I'm new to Crystal, and am working through the documentation as I build out a test project to help me reinforce some of the principles inside Crystal.

I need to be able to iterate x number of times in a loop. The x is arbitrary, not tied to an arrays length, but is a set value at the time of the programs execution.

What's the Crystal way to do this?

I know that I can setup a while and get the behavior I'm looking for, but is there a specific way this is meant to be implemented in Crystal?

For example, in Ruby, you could say x.times { }or in Python you could say for num in range(x).

Solution

  • There is an x.times {} in Crystal too.
