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

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

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 
const get_Meridiem_Suffix_Of_Integer = num =>
  num === 0 || num === 24
    ? 12 + 'am'
    : num === 12
      ? 12 + 'pm'
      : num < 12
        ? (num % 12) + 'am'
        : (num % 12) + 'pm';

console.log(get_Meridiem_Suffix_Of_Integer(0));
console.log(get_Meridiem_Suffix_Of_Integer(11));
console.log(get_Meridiem_Suffix_Of_Integer(13));
console.log(get_Meridiem_Suffix_Of_Integer(25));

Sample Output:

12am
11am
1pm
1pm

JavaScript: Tips of the Day

Chunks an array into n smaller arrays

Example:

const tips_chunkIntoN = (arr, n) => {
  const size = Math.ceil(arr.length / n);
  return Array.from({ length: n }, (v, i) =>
    arr.slice(i * size, i * size + size)
  );
}
console.log(tips_chunkIntoN([1, 2, 3, 4, 5, 6, 7,8], 4)); 

Output:

[[1,2],[3,4],[5,6],[7,8]]
