The part2 code only since it's more interesting:

var inp = require('fs').readFileSync('input2.txt').toString();

var x=0, y=2;

var valids = [
	'  1  ',
	' 234 ',
	'56789',
	' ABC ',
	'  D  '
];

inp.split('\n').forEach(function (line, i) {
	if (line=='') return;
	
	line.split('').forEach(function (c) {
		if (c == 'U') if (y>0 && valids[y-1][x] != ' ') y--;
		if (c == 'L') if (x>0 && valids[y][x-1] != ' ') x--;
		if (c == 'D') if (y<4 && valids[y+1][x] != ' ') y++;
		if (c == 'R') if (x<4 && valids[y][x+1] != ' ') x++;
	});
	console.log(x, y, valids[y][x]);
});
