Adding hours to JavaScript Date object?

Question

It amazes me that JavaScript\'s Date object does not implement an add function of any kind.

I simply want a function that can do this:

var now = Date         


        

Answer 1

This is a easy way to get incremented or decremented data value.

const date = new Date()
const inc = 1000 * 60 * 60 // an hour
const dec = (1000 * 60 * 60) * -1 // an hour

const _date = new Date(date)
return new Date( _date.getTime() + inc )
return new Date( _date.getTime() + dec )
