Errors and Exceptions

• Code #1: If in Date() constructor we do not give any second, still setSeconds() function set new second which is given as its parameter.

  // Here second has not been assigned // while creating Date object var dateobj = new Date('October 13, 1996');    // new second of 51 is being set in above Date // Object with the help of setSeconds() function dateobj.setSeconds(51);    // new second from above Date Object is // being extracted using getSeconds() var B = dateobj.getSeconds();    // Printing new Second console.log(B);

  Output:

  > 51

• Code #2: If nothing as parameter is given in Date() constructor, still setSeconds() function set second but month, year, date etc become current ones.

  // Here nothing has been assigned // while creating Date object var dateobj = new Date();    // new second of 42 is being set in above Date // Object with the help of setSeconds() function dateobj.setSeconds(42);    // Seconds from above Date Object is // being extracted using getSeconds() var B = dateobj.getSeconds();    // month from above Date Object is // being extracted using getMonth() var C = dateobj.getMonth();    // date from above Date Object is // being extracted using getDate() var D = dateobj.getDate();    // year from above Date Object is // being extracted using getFullYear() var E = dateobj.getFullYear();    // Printing new seconds console.log(B);    // Printing current month console.log(C);    // Printing current date console.log(D);    // Printing current year console.log(E);

  Output:

  > 42
  > 3
  > 1
  > 2018

  Here 42 is the new seconds, 3 is the current month i.e April, 1 is the current date and 2018 is the current year.

• Code #3: If value of second 66 is given as the parameter of setSeconds() function, It will set 6 as the second because second range is form 0 to 59 and ( 66%60 = 6).

  // Here date has been assigned // while creating Date object var dateobj = new Date('October 13, 1996 05:35:32');    // new second of 66 is being set in above Date // Object with the help of setSeconds() function dateobj.setSeconds(66);    // seconds from above Date Object is // being extracted using getSeconds() var B = dateobj.getSeconds();    // Minute from above Date Object is // being extracted using getMinutes() var C = dateobj.getMinutes();    // Printing new seconds console.log(B);    // Printing minutes console.log(C);

  Output:

  > 6
  > 36

  Here 6 is the new second and minutes becomes 36 from 35 because second range is form 0 to 59. So when 66 is passed as parameter to the setSeconds() function, it will set the seconds in the respective Date object to (66%60 = 6) and will increment the minutes in the respective Date object by (66/60 = 1).
