Answer 1

Here's a solution

var date = '20170721'; 
var year = date.slice(0,4), 
month = date.slice(4,6), 
day = date.slice(-2);

// create new Date obj
date = new Date(year, month, day);

// format using toLocaleDateString
console.log(new Date(year, month, day).toLocaleDateString('en-GB'));

// custom format
console.log(date.getFullYear() + ' ' + (date.getMonth()) + ' ' + date.getDate())


//output 2017 JUL 21
