list

  • We can do the equivalent of PHP’s list function in Ruby using parallel assignment. In Ruby we can assign comma separated variables to elements of an array using the normal assignment operator.

    PHP

    $attributes = array('Joe', 25, 'blonde');
list($name, $age, $hair) = $attributes;
print $name; // => 'Joe'
print $age;  // => 25
print $hair; // => 'blonde'

    Ruby

    attributes = ["Joe", 25, "blonde"]
name, age, hair = attributes
puts name # => "Joe"
puts age  # => 25
puts hair # => "blonde"
