TypeScript - get current time
0 points
In TypeScript Date class is useful to get current time.
Quick solution:
xxxxxxxxxx1
const now: number = Date.now();2
3
console.log('Current unix millisecond time: ' + now);
xxxxxxxxxx1
const now: Date = new Date();2
3
console.log('Current unix millisecond time: ' + now.getTime());4
console.log('Current date: ' + now.toDateString());5
console.log('Current time: ' + now.toTimeString());6
console.log('Current date & time: ' + now.toString());Note: during using
to...Stringmethods it is necessaryto be careful because of specific formatting of data and time on the locale.
renderNumber method can be replaced with built-in padStart method.
