2. Word operators

unless, until, loop, and isnt

horizon-dark

until count is 10
  count := count + 1

loop
  break unless active

if value isnt null and value is not 0
  process value

atom-one-dark

until count is 10
  count := count + 1

loop
  break unless active

if value isnt null and value is not 0
  process value

github-dark

until count is 10
  count := count + 1

loop
  break unless active

if value isnt null and value is not 0
  process value

dracula

until count is 10
  count := count + 1

loop
  break unless active

if value isnt null and value is not 0
  process value

nord

until count is 10
  count := count + 1

loop
  break unless active

if value isnt null and value is not 0
  process value

github

3. Pipe chains

the |> operator chaining function calls

horizon-dark

result := [1, 2, 3]
  |> filter (n) -> n > 1
  |> map (n) -> n * 10
  |> reduce (a, b) -> a + b

atom-one-dark

result := [1, 2, 3]
  |> filter (n) -> n > 1
  |> map (n) -> n * 10
  |> reduce (a, b) -> a + b

github-dark

result := [1, 2, 3]
  |> filter (n) -> n > 1
  |> map (n) -> n * 10
  |> reduce (a, b) -> a + b
