Sorry if this duplicated.
I saw +new Date in a github project then I try it out.
It's return timestamp in type of number.
While new Date() return time format in string.
So what is the meaning of +new Date syntax and how to implement in my own module
This is standard javascript. Not node specific
When calling a constructor with new the parenthesis are optional if it takes no arguments
function MyObject () {}
new MyObject();
new MyObject; // these both create an object
The + is just a shorthand way of casting to a number.
Its the unary plus operator simmilar to the unary minus operator in -5
+'123' === 123 // true
In the case of +new Date this casts a Date object to a number or the current number of milliseconds since the unix epoch. Result is the same as date.getTime().
