### re: Daily Challenge #50 - Number Neighbor VIEW POST

My solution in js

const numberNeighbour = (num) => {
const neighbours = [];
num.split('').forEach((value, index) => {
if(parseInt(value) - 1 > 0) {
let prevNum = num.split('');
prevNum[index] = parseInt(value) - 1;
prevNum = prevNum.join('');
neighbours.push(prevNum.slice(0, 3) + "-" + prevNum.slice(3, 6) + "-" + prevNum.slice(6));
}
if(parseInt(value) + 1 < 10) {
let nextNum = num.split('');
nextNum[index] = parseInt(value) + 1;
nextNum = nextNum.join('');
neighbours.push(nextNum.slice(0, 3) + "-" + nextNum.slice(3, 6) + "-" + nextNum.slice(6));
}
});
return neighbours;
};

numberNeighbour('5555555555');
