In order to take the Timestamps in javascript yuo can write this kind of code:
// Usual Way
var d = new Date();
timestamp = d.getTime();
But I found that is it also possible to get the same result in this way:
// The shortest Way
timestamp = +new Date();
Can someone help me to understand how the Shortest Way works?
That is the unary plus operator. It attempts to convert the argument that follows into a number if it isn't already a number. The Date object implements a method that allows it to be converted to a number, which is the timestamp identical to the getTime() method.
A more legible and obvious way of getting a timestamp without using an extra variable is to use parentheses:
var timestamp = (new Date()).getTime();
valueOf method.JavaScript is a dynamic typed language, and it will try conversions appropriate to the context.
When adding a unary plus in front of the Date Object it will be converted to a number.
