Is it possible to generate a Date object from a predetermined string in typescript?

I have a string with values separated by commas, and I'm trying to create a Date object from it. It seems like this is not doable -- can someone verify this and provide a solution if possible?
This code snippet doesn't work :

let dateString='2017,3,22,0';
let dateFromString = new Date(dateString);

However, this code works fine (when passing individual numbers) :

let dateFromString = new Date(2017,3,22,0);

And this code also works :

let dateString = '2008/05/10 12:08:20';
let dateFromString = new Date(dateString);

The objective is to generate a Date object from a consistent string format. Is there a way to achieve this?

Can I generate a Date object from a standard string that uses only one type of separator (comma, colon, slash, etc.)?

Answer №1

If your coding environment supports ES6 (e.g. Babel, TypeScript, up-to-date Chrome/Firefox), you have the option to utilize the .split(',') method on strings to split them into arguments as shown below:

const dateString = '2019,8,15,0';
const date = new Date(...dateString.split(','));  // creates a date object for August 15, 2019

For compatibility with ES5, you can use the following approach:

var dateString = '2019,6,7,0';
var date = new (Function.prototype.bind.apply(Date, [null].concat(dateString.split(','))));

To understand how the .bind.apply technique functions in conjunction with new, refer to this insightful discussion: Use of .apply() with 'new' operator. Is this possible?
