Using JSONata in JavaScript?

Question

I am a JavaScript student and came across JSONata recently.

I am creating an application where our backend requires us to send the date time field in following format: "2019-04-25T11:36:30.254Z"

I see that we can get this using JSONata by using $now() function.

I am not sure how we can use JSONata with JavaScript. Or is there a way to get date time in above format using JavaScript?

I tried below till now but not successful:

    var jsonata = require("jsonata");
    var date_now = jsonata("$now");
    console.log(date_now)

I also tried simple javascript date time objects but that does not give me the required format.

To invoke JSONata, you need to do the following...

var jsonata = require("jsonata");
var date_now = jsonata("$now()").evaluate();
console.log(date_now)

However, if you only need it to format the date to ISO8601, then using JSONata is probably a bit overkill.

You can use the native JavaScript method Date.toISOString() like in the following example:

let d = new Date()
console.log(d.toISOString())

You can also use .toJSON

var jsonDate = (new Date()).toJSON();
console.log(jsonDate);
