JavaScript: Create tomorrow's date in a string representation

JavaScript fundamental (ES6 Syntax): Exercise-119 with Solution

String for Tomorrow's Date

Write a JavaScript program to create tomorrow's date in a string representation.

• Use new Date() to get the current date.
• Increment it by one using Date.prototype.getDate() and set the value to the result using Date.prototype.setDate().
• Use Date.prototype.toISOString() to return a string in yyyy-mm-dd format.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2

// Define the 'tomorrow' function.
const tomorrow = (long = false) => {
  // Create a new Date object representing tomorrow's date.
  let t = new Date();
  t.setDate(t.getDate() + 1);

  // Format the date string in YYYY-MM-DD format.
  const ret = `${t.getFullYear()}-${String(t.getMonth() + 1).padStart(2, '0')}-${String(t.getDate()).padStart(2, '0')}`;

  // Return the date string with or without the time component.
  return !long ? ret : `${ret}T00:00:00`;
};

// Example usage: Get tomorrow's date.
console.log(tomorrow());      
console.log(tomorrow(true));
