Introduction

ZJS provides console API's which match Node.js' Console module. We describe them here as there could potentially be minor differences.

Note that the console API's do not support format specifiers (e.g. %d, %f etc.).

API Documentation

assert

void assert(boolean value, optional string message);

Assert/throw an error if value is false.

error

void error(optional string data);

Prints data to stderr with newline. (On Zephyr this will just print to stdout).

warn

void warn(optional string data);

Alias for console.error()

log

info

void info(optional string data);

time

void time(string label);

Starts a timer used to compute the duration of an operation. The label string is used to reference the timer when calling console.timeEnd().
