array.compat() methodarray.compact() is a Ruby method that removes all nil values from an array and returns the array without any nil values.
This method does not change or modify the original array. It only returns a copy of the array without
nilvalues.
array.compact()
The compact() method is only called on arrays. It takes no parameters.
A copy of array is returned without any nil value in it.
In the below code, we create different arrays. Then, we call the compact() method on them. Finally, we print the returned values to the console.
# create different arraysarr1 = [1, 2, 3, 4, 5, nil]arr2 = ["a", "b", "c", "d"]arr3 = [true, false, nil]arr4 = ["nil", "true", "false"]arr5 = [nil, nil, nil]arr6 = ["Python", "Java", nil, "JavaScript"]# remove nil values with compact() methoda = arr1.compact()b = arr2.compact()c = arr3.compact()d = arr4.compact()e = arr5.compact()f = arr6.compact()puts "#{arr1}.compact() = #{a}"puts "#{arr2}.compact() = #{b}"puts "#{arr3}.compact() = #{c}"puts "#{arr4}.compact() = #{d}"puts "#{arr5}.compact() = #{e}"puts "#{arr6}.compact() = #{f}"
