Write a function which can convert time from 12 hours format to 24 hours format.
Write a function called convertTo24HrsFormat
which take time
as parameter in HH:MMAM
format. for example, 12:10AM
.
// Function to convert 12Hrs time to 24Hrs time.
function convertTo24HrsFormat(time) {
let timeArray = time.split(':');
let hour = Number(timeArray[0]); // Convert hour into number from string
if (time.endsWith('PM')) {
// if hour is not 12 then add 12 hour.
hour = hour !== 12 ? hour + 12 : hour;
} else {
// if time is AM and if hour is 12 then subtract 12 hour.
hour = hour === 12 ? hour - 12 : hour;
}
time = `${hour.toString().padStart(2, 0)}:${timeArray[1].slice(0, -2)}`;
return time;
}
Function convertTo24HrsFormat
takes time
as parameter and split it into two parts where first part will be HH
and second part will be MMAM
or MMPM
. After that convert hours into Number data type and check condition using string endsWith()
method. if condition and manipulate time hours and after that remove AM or PM and return time in 24Hrs format.
