JavaScript Date Object With Example

JavaScript Date Object

The Date object is a data type built into the JavaScript language. Once a Date object is created, a number of methods are available to operate on it.

Syntax:

  • new Date() - This constructor creates a Date object set to the current date and time.
  • new Date(milliseconds) - When one numeric argument is passed, it is taken as the internal numeric representation of the date in milliseconds, as returned by the getTime() method.
  • new Date(datestring) - When one string argument is passed, it is a string representation of a date, in the format accepted by the Date.parse() method.
  • new Date(year,month,date[,hour,minut,second,millisecond])-The parameters on square brackets are optional.

Date Properties:


  • Constructor - Specifies the function that creates an object's prototype.
  • Prototype - The prototype property allows you to add properties and methods to an object
