All you have to do is move a[1] and a[2] to the end

var a = "#AABBCCDD";

var b = "#"+a.slice(3,9)+a[1]+a[2];

If you're dealing with a string #FF123456

let x = '#FF123456';
console.log(x.replace(/#(..)(......)/, '#$2$1'));

If, however, x is a number, 0xFF123456 - 

let x = 0xFF123456
console.log(`#${(x & 0x0FFFFFF).toString(16).padStart(6, '0')}${(x >>> 24).toString(16).padStart(2, '0')}`);
