JavaScript : Convert an integer to a suffixed string, adding am or pm based on its value

JavaScript fundamental (ES6 Syntax): Exercise-50 with Solution

Integer to Suffix String with am/pm

Write a JavaScript program to convert an integer to a suffixed string, adding am or pm based on its value.

• Use the modulo operator (%) and conditional checks to transform an integer to a stringified 12-hour format with meridiem suffix.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2
// Define a function 'get_Meridiem_Suffix_Of_Integer' that returns the meridiem suffix ('am' or 'pm') of an integer.
const get_Meridiem_Suffix_Of_Integer = num =>
  // Check various cases and return the appropriate suffix.
  num === 0 || num === 24
    ? 12 + 'am'
    : num === 12
      ? 12 + 'pm'
      : num < 12
        ? (num % 12) + 'am'
        : (num % 12) + 'pm';

// Test cases
console.log(get_Meridiem_Suffix_Of_Integer(0));  // Output: '12am'
console.log(get_Meridiem_Suffix_Of_Integer(11)); // Output: '11am'
console.log(get_Meridiem_Suffix_Of_Integer(13)); // Output: '1pm'
console.log(get_Meridiem_Suffix_Of_Integer(25)); // Output: '1pm'

Output:

12am
11am
1pm
1pm
