getMeridiemSuffixOfInteger

Converts 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.

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

getMeridiemSuffixOfInteger(0); // "12am"
getMeridiemSuffixOfInteger(11); // "11am"
getMeridiemSuffixOfInteger(13); // "1pm"
getMeridiemSuffixOfInteger(25); // "1pm"
