# create an array

# print each element squared
arr each: |x| {
  x squared println
}

# display each element with its index in the array
arr each_with_index: |x i| {
  "Index " ++ i ++ " -> " ++ x println
}

# print the array of squared elements
arr map: 'squared . inspect println

# print the array of doubled elements
arr map: 'doubled . inspect println

# print array of all elements smaller than 4
arr select: |x| { x < 4 } . inspect println

# print array of all elements that are not smaller than 4
arr reject: |x| { x < 4 } . inspect println

# prints: [5, 6]
arr take_while: |x| { x < 5 } . inspect println

"testing reduce:init_val: " print
arr reduce: |acc x| { acc * x } init_val: 1 . println # same as: 1*1*2*3*4*5*6

"testing any?: " print
arr any?: |x| { x > 3 } . println # prints: true

"testing all?: " print
arr all?: |x| { x < 7 } . println # prints: true

"testing from:to: " print
arr [[3,5]] . inspect println # prints: [4, 5, 6]

# some other handy methods
"testing size: " print
arr size println # prints: 6

"testing to_s: " print
arr to_s println # prints: 123456

"testing inspect: " print
arr inspect println # prints: [1, 2, 3, 4, 5, 6] : Array
