create a date object from input which has only hours and minutes in the form `01h23` in typescript

You can create a Date object using the setHours and setMinutes methods in TypeScript.

Here's an example code snippet:

index.ts
const inputTime = '01h23';

// extract hours and minutes from input string
const hours = parseInt(inputTime.substring(0, 2));
const minutes = parseInt(inputTime.substring(3, 5));

// create a new Date object with current date and extracted time
const date = new Date();
date.setHours(hours);
date.setMinutes(minutes);

console.log(date); // outputs the current date with extracted time

In this example, we start by extracting the hours and minutes from the input string using parseInt and substring. Then, we create a new Date object with the current date, and set the hours and minutes using the extracted values. Finally, we log the resulting Date object to the console to verify that it was created correctly.
