class Console extends Object

The console module provides a simple debugging console that is similar to the JavaScript console mechanism provided by web browsers.

The module exports two specific components:

  • A Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
  • A global console instance configured to write to stdout and stderr. Because this object is global, it can be used without calling require('console').

    A simple assertion test that verifies whether value is truthy.

    A simple assertion test that verifies whether value is truthy. If it is not, an AssertionError is thrown. If provided, the error message is formatted using util.format() and used as the error message.

    Example:

    1. console.assert(value[, message][, ...])

  6. def assert(value: Any, message: String, args: Any*): Unit

    Uses util.inspect() on obj and prints the resulting string to stdout. This function bypasses any custom inspect() function defined on obj

    Example:

    1. console.dir(obj[, options])

  26. def time(label: String): Unit

    Starts a timer that can be used to compute the duration of an operation.

    Starts a timer that can be used to compute the duration of an operation. Timers are identified by a unique label. Use the same label when you call console.timeEnd() to stop the timer and output the elapsed time in milliseconds to stdout. Timer durations are accurate to the sub-millisecond.

    Example:

    1. console.time(label)

  27. def timeEnd(label: String): Unit

    Stops a timer that was previously started by calling console.time() and prints the result to stdout
