hi friends i have a question when i use function date in Schema (mongoose) date: { type: Date , default: Date.now }, date display like this 2018-05-07T213057.642Z who have idea how i display date well format

That date is formatted as ISO. You can use it to create a data object in JavaScript:

var date = new Date('2018-05-07T21:30:57.642Z')

. If you have a JavaScript date object you can get the iso

date.toISOString()

Or you can use it with an npm that helps format dates. I like moment: https://www.npmjs.com/package/moment
