Date not working in Typescript but working in browser console

I get this error Supplied parameters do not match any signature of call target. when I try to do this in my TypeScript file in Angular2. 

console.log(Date(this.field.sowing_date));

If I execute the same thing in the Chrome Debugger I don't get any problem.

Do you know what is?

I am using:

"@angular/core": "^2.4.0" "@angular/cli": "^1.0.0-rc.4", "@angular/compiler-cli": "^2.4.0",

You cannot pass a parameter to Date when you don't use it as a constructor (without new):

In JavaScript:

Date(); // returns current date as string
Date("1/1/2017"); // ignores the parameter and returns the current date as string

TypeScript rightfully complains because Date(param) is not a valid way to call Date.

You can use Date in TypeScript like:

let currentDateAsString : string = Date(); // if you want the current date string
let parsedDate: Date = new Date(this.field.sowing_date); // if you want to parse it.

MDN documentation on Date which explains the ways Date can be used: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date
