I am learning ruby

Before get started with Ruby on Rails, I am just learning ruby programming language and I found the following facts about ruby. I am writing basics of ruby programming which I learned today.

1. Variable

• Ruby variables are dynamic typing and duck typing
• Can be define simply assigning value to the variable

count = 10 
awesome_count = 20 // correct convention
awesomeCount = 20 // Wrong convention

• Yay ! we do not need any semicolon here
• Common convention for the varible define is snake case not camel case
• 2 Space is common practice instead of 4 space in code

2. Comment in Ruby

• Writing comment in ruby is quite simple and straight forward
• For e.g.

# This is ruby comment

3. Function in Ruby

• Function can be define using 'def' like this

def double(value); value * 2; end
double(2) // results 4

• We do not need return statement to return value too
• In above example single line function and statement are seperated by semi-colon please do not confused on it
• For the multiple line we can write like this

def double(value)
 value * 2
end
double(2) // results 4

Thank you ! Would you like to suggest me 1 book to read to get better knowledge on ruby ?

I’ve always been a fan of Eloquent Ruby. Unfortunately, it hasn’t been updated in some time. Still might be worth checking out.

The Rails Way is great if you’re getting into Rails.
