 This replaces all 's' in the string to 'th'.
 
+_.split_ method returns all words in a string as an array. If text is given as parameter, it will divide the string wherever it sees that bit of text. The test is called _delimiter_.
+```ruby
+words = text.split(" ")
+```
+_text_ is a string and _words_ is an array. Space is delimiter here.

 ## Comments
 Single line comments are written with hash(#) in the start. Multi-line comments start with _=begin_ and end with _=end_ .

-You have to give a condition inside the block which will be used to decide when to break the loop.
+A condition is given inside the block which will be used to decide when to break the loop.
+The __next__ keyword can be used to skip over certain steps in the loop.
+```ruby
+i = 20
+loop do
+  i -= 1
+  next if i%2!=0
+  	puts "#{i}"
+  break if i <= 0
+end
+```
+This code snippet will print only even numbers from 18 to 0.

+Arrays in Ruby are declared as:
+```ruby
+my_array = [1,2,3,4,5]
+```
+__.each__ method is more powerful iterator.
+```ruby
+array = [1,2,3,4,5]
+array.each do |x|
+  x += 10
+  print "#{x}"
+end
+```
+_do_ and _end_ keywords can be replaced by curly braces {}.
+
+The __.times__ method is like a super compact for loop: it can perform a task on each item in an object a specified number of times.
+```ruby
+10.times do
+  print "Hello there!"
+end
+```
