**Agenda Iterators & Blocks**

#Bad Git commits & Good Git Commits from Andre

#Intro

#Recap
 - puts and console
 - Arrays
 - CRUD arrays

 - Range
 - .. ...

#Iterators .each
 - .each iterate over musicians display "Hello #{musican}"

#Iterators .map
 - [] -> []
 - .upcase musicans, save to new array
  2nd part
 - .map to make array with first name of musicians

#Iteratorgit .conut
 - # [] -> integer
 - returns integer of sum of condition == true

#Iterator .select & reject
 - # [] -> []
 - returns new array where condition == true

##!! do not return inside the iterators!!##

## Your job is now to search for new iterators for you excercises
## Search inside class of arrays in ruby docs
## Search inside enumerable - any


#Blocks
 - Block is just an argument to a method
 - run code for method
 - Block returns something


#Yield
 - Yield will run a block of code passed as an argument
 - Yield creates an extra "parameter" for a mathod, that will take the block as the argument. for the created parameter.
 - Implement bad Timer
 - Implement time with yield

 - Implement yield_greet.rb
