Console API

Console.log(anything)

Output a string or object to standard output followed by a newline. Suitable for writing to logs, or for outputting user messaging in command line applications. If you pass a string, it will not be wrapped in quotes. If you pass an object, Console.log will attempt to print the object dynamically. Strings deep in objects will be wrapped in quotes.

let log: 'a => unit;

Console.out(anything)

Same as Console.log but attempts to avoid printing a final newline. Not all backends will support omitting the newline (such as in the browser where console only supports outputting with final newlines.)

let out: 'a => unit;

Console.debug(anything)

Same as Console.log but used for developer-facing messaging to standard out. Suitable for writing to log files. In production mode, would typically be suppressed entirely. Custom Console.t implementations may implement custom behavior for Console.debug that behaves differently from Console.log.

let debug: 'a => unit;

Console.error(anything)

Same as Console.log but writes to stderr.

let error: 'a => unit;

Console.warn(anything)

Currently the same as Console.error but will eventually be able to be suppressed via a "log level".

let warn: 'a => unit;
