NAME

Data::Sah::Compiler::js::TH::date - js's type handler for type "date"

VERSION

This document describes version 0.86 of Data::Sah::Compiler::js::TH::date (from Perl distribution Data-Sah), released on 2016-07-22.

DESCRIPTION

Unlike in perl compiler where the date type can be represented either as int (epoch), DateTime object or Time::Moment object, in js compiler we only represent date with the Date object.

Date() accept various kinds of arguments, including:

• Date()

  Current date.

• Date(milliseconds epoch)

• Date(year, month, date, hour, minute, sec, millisec)

  But year is 114 utk 2014, month=0 for January.

• Date(datestring)

  This saves us from doing date parsing ourselves.

• Date(another Date object)

But note that if the arguments are invalid, Date() will still return a Date object, but if we try to do d.getMonth() or d.getYear() it will return NaN. This can be used to check that a date is invalid: isNaN(d.getYear()) or simply <isNaN(d)>.

To compare 2 Date object, we can use d1 > d2, d1 < d2, but for anything involving equality check, we need to prefix using +, +d1 === +d2.
