When i'm setting up date object using the below statement the output showing different in nodejs. Can you please help me to understand why it is like this. And how i need to pass to print right value.
var date1= new Date(2017,01,01);
var date2= new Date(2017,01,31);
console.log("2017-01-01 is printed as ==>",date1);
console.log("2017-01-31 is printed as ==>",date2);
Output
2017-01-01 is printed as ==> 2017-01-31T18:30:00.000Z
2017-01-31 is printed as ==> 2017-03-02T18:30:00.000Z
Printing your logs like this
console.log("2017-01-01 is printed as ==>"+date1);
console.log("2017-01-31 is printed as ==>"+date2);
will give you your expected logs
It is because console log will take date as object of date while using comma and while using + it will apply object.toString() to date object.
Month parameter starts from 0 (January) to 11 (December) so if you want to get 2017-01-01 you need to use:
var date1 = new Date(2017, 0, 1)
More info here: https://developer.mozilla.org/es/docs/Web/JavaScript/Referencia/Objetos_globales/Date
var date1= new Date(2017,0,1); var date2= new Date(2017,0,31); console.log("2017-01-01 is printed as ==>",date1); console.log("2017-01-31 is printed as ==>",date2); Output 2017-01-01 is printed as ==> 2016-12-31T18:30:00.000Z 2017-01-31 is printed as ==> 2017-01-30T18:30:00.000Z
console.log("2017-01-01 is printed as ==>"+date1); console.log("2017-01-31 is printed as ==>"+date2); ?
date1 and date2 as an object to the log method while using + will invoke object.toString on the date object and print the date. Hence such different behaviors. This discussion on stack might give you more explanation.
