## console For printing to stdout and stderr. Similar to the console object functions provided by most web browsers, here the output is sent to stdout or stderr. ### console.log() Prints to stdout with newline. This function can take multiple arguments in a `printf()`-like way. Example: console.log('count: %d', count); If formatting elements are not found in the first string then `util.inspect` is used on each argument. See [util.format()](util.html#util.format) for more information. ### console.info() Same as `console.log`. ### console.warn() ### console.error() Same as `console.log` but prints to stderr. ### console.dir(obj) Uses `util.inspect` on `obj` and prints resulting string to stderr. ### console.time(label) Mark a time. ### console.timeEnd(label) Finish timer, record output. Example console.time('100-elements'); for (var i = 0; i < 100; i++) { ; } console.timeEnd('100-elements'); ### console.trace() Print a stack trace to stderr of the current position. ### console.assert() Same as `assert.ok()`.
