convert strings to numbers inside array JavaScript

Question

I have an array of strings:

["5:17", "8:22", "3:34", "5:23", "7:12", "7:24", "6:46", "4:45", "4:40", "7:58", "11:51", "9:13", "5:50", "5:52", "5:49", "8:57", "11:29", "3:07", "5:59", "3:31"]

How can I convert the strings to numbers?

This look like a time in string, can you please tell your expected output? — Nitish Narang

What i see is, it's time - 5:17 means 5 hours and 17 minutes, now when displaying in number format, either you can display in minutes or in hours. What are you expecting here? — Nitish Narang

Great!!! Then it will be a string as you can't denote colon ':' as a number :) — Nitish Narang

You can use "map" as below

arr.map(d => {
    let [min, sec] = d.split(':')
    return +min * 60  + +sec
})
