Formatting Strings

Build a formatted string using the first argument as a printf-like format.

util.format('%s %d', 'hello', 32);  // 'hello 32'

Console Logging

util.log('message');
// => 30 Dec 22:34:31 - message

util.debug('message');
// => DEBUG: message

util.error('message');
// => message

util.puts('message');
// => message

Inspecting Objects

Build a string representation of object, which is useful for debugging.

console.log(util.inspect(util, true, null));

Type Checking

Check if an object is of a particular type.

util.isArray([]);

util.isRegExp(/some regexp/);

util.isDate(new Date());

util.isError(new Error());

Class Inheritance

Inherit the prototype methods from one constructor into another.

function MyStream() {
  events.EventEmitter.call(this);
}

util.inherits(MyStream, events.EventEmitter);
