storeLocations1 = [
  'Orlando'

  'Sanford'
]

# Beware, this doesn't compile correctly:
# storeLocations.forEach(location, index) ->
# It uses it as a forEach(location, index) call with a () => {} callback

# So be sure to add the space.
storeLocations1.forEach (location, index) ->
  console.log "Location #{index}: #{location}"

# Or use something more idiomatic:
for location, index in storeLocations1
  console.log "Location #{index}: #{location}"

# List comprehensions
console.log "Location #{index}: #{location}" for location, index in storeLocations1

# In this case, the parentheses are essential
storeLocations2 = ("#{loc}, FL" for loc in storeLocations1)
# Without them, the whole "storeLocations = ..." part is run for each loc.
console.log storeLocations2

geoLocate = (loc) ->
  return "#{loc}, USA"

# Applying a filter to a list comprehension
console.log (geoLocate(loc) for loc in storeLocations1 when loc isnt 'Sanford')

storeLocations3 = (loc for loc in storeLocations1 when loc isnt 'Sanford')
console.log(storeLocations3)
