Javascript question

Question

I have a string of time inside a variable like
string='03:47am-04:56am'. we need to find the difference between time in minutes.
Can anyone help me how to solve this using javascript

Answer 1

const time= '03:47am-04:56am'
const [firstTime,secondTime]=time.split("-")

const [firstTimeHour,firstTimeMinute]=firstTime.split(':')
const [secondTimeHour,secondTimeMinute]=secondTime.split(':')

const result = (parseInt(secondTimeHour)*60+parseInt(secondTimeMinute))-(parseInt(firstTimeHour)*60+parseInt(firstTimeMinute))
console.log(`${result} minutes`)

What is your attempt, even if it's just pseudocode so you can be pointed in the right direction?

You need to convert data from string, if your string is always in same format you can separate tham by separator (-), you can use str.split("-") for this, but only if you will always have "-" in string, if not you should check is "-" in string before moving forward with code.
More about split method:

Now you will have array with 2 data
let data = ["03:47am","04:56am"]
You can now check is data am or pm, or convert to 24h format to calculate easier.
For example if first data is pm, 03:00pm - 02:00am difference is not 1 hour it is 13h, thats why I will convert to 24h format.

To separate hours and minutes you can also use str.split(":") but now separator is :

Try to code it, if you have problem post your code attempt so we can help you.
