JavaScript: Convert a given number to hours and minutes

JavaScript Basic: Exercise-51 with Solution

Transform Number to Hours and Minutes

Write a JavaScript application that transforms a numerical value into hours and minutes.

This JavaScript application converts a given numerical value representing minutes into hours and minutes. It calculates the hours by dividing the total minutes by 60 and the remaining minutes using the modulus operator, then formats and displays the result.

Sample Solution:

JavaScript Code:

// Define a function named time_convert with parameter num
function time_convert(num)
 { 
  // Calculate the number of hours by dividing num by 60 and rounding down
  var hours = Math.floor(num / 60);  

  // Calculate the remaining minutes by taking the remainder when dividing num by 60
  var minutes = num % 60;

  // Return the result as a string in the format "hours:minutes"
  return hours + ":" + minutes;         
}

// Log the result of calling time_convert with different numeric inputs to the console
console.log(time_convert(71));
console.log(time_convert(450));
console.log(time_convert(1441)); 

Output:

1:11
7:30
24:1

ES6 Version:

// Define a function named time_convert with parameter num
const time_convert = (num) => {
    // Calculate hours by dividing num by 60 and rounding down
    const hours = Math.floor(num / 60);
    
    // Calculate minutes by taking the remainder when num is divided by 60
    const minutes = num % 60;
    
    // Return the result as a string in the format "hours:minutes"
    return `${hours}:${minutes}`;
};

// Log the result of calling time_convert with the given numbers to the console
console.log(time_convert(71));
console.log(time_convert(450));
console.log(time_convert(1441));
