hhmm-to-mins-and-back.js
const hhmmToMinutes = hhmm => hhmm.split(':').map((c,i)=>(i===0?parseInt(c)*60:parseInt(c))).reduce((a,b)=>(a+b),0)
const minutesToHhmm = min => (`${Math.floor(min/60)<10?0:''}${Math.floor(min/60)}:${min%60<10?0:''}${min%60}`)
// hhmmToMinutes('8:59') //539 (480+59)
// minutesToHhmm(539) //'08:59'
