Programming is FUN!

Block is basically anonymous method that gets called from another method. If you have some code that executes passed in method like this:

def execute_method_in_block(named_method)
    named_method.call
    named_method.call
end

execute_method_in_block Proc.new {puts "Hello, blocks are cool!"}

You can write it like this using blocks:

def execute_method_in_block
    yield
    yield
end

execute_method_in_block  {puts "Hello, blocks are cool!"}

We’ve lost “Proc.new” and a method name, we are just saying

Whenever you find yield, execute block that is defined within braces.

You might be wondering what’s the fuss all about, (more…)
