catch()

catch(callable) → CatchResult

Executes the callable, which must not require any arguments. Returns a CatchResult indicating success or failure and providing the returned result or the error message respectively.

print()

print(text)

Prints its text to standard output (which might be redirected by the application).

printf()

printf(fmt, [values...])

Formats its arguments given the fmt string, and prints the result to standard output (which might be redirected by the application).

See String Formatting for the format string syntax.

println()

println([text])

Prints its text followed by a line separator to standard output (which might be redirected by the application).
