Get meridiem suffix of integer	snippet	javascript	date	dark-leaves-4	2020-10-19T22:49:51+03:00

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'
