Example
This example inserts a new line (\n
) after each iteration. Specifically,
it uses map
to iterate over the result of to(1, 10)
, [1,2,3,4,5]
, then
writes the specified content ("Line $"), which includes the unnamed variable
$
for each number in the array.
Note that without writeLinesWith "UTF-8"
, the expression
{ lines: to(1, 10) map "Line $" }
simply returns
an array of line numbers as the value of an object:
{ "lines": [ "line 1", "line 2", "line 3", "line 4", "line 5" ] }
.
