Can I create a Date object from a predefined string (typescript)? -

i have value returned in string (numbers separated commas) , i'd make date object out of it. looks not possible, can confirm and/or suggest me solution.
not work :

let datestring='2017,3,22,0'; let datefromstring = new date(datestring); 

this works though (when pass list of numbers) :

let datefromstring = new date(2017,3,22,0); 

and works :

let datestring = '2008/05/10 12:08:20'; let datefromstring = new date(datestring); 

the goal create date object uniform string. possible ?

can create date object predefined string, has 1 type of separator (comma, colon, slash or whatever) ?

if environment compatible es6 (eg. babel, typescript, modern chrome/firefox etc), can use string's .split(',') , decompose array arguments following:

const datestring = '2017,3,22,0'; const date = new date(...datestring.split(','));  // date object 2017/03/22 

es5 compatible version:

var datestring = '2017,1,2,0'; var date = new (function.prototype.bind.apply(date, [null].concat(datestring.split(',')))); 

as how .bind.apply method works new, can take @ use of .apply() 'new' operator. possible?
