Tests:

Classic For Loop
for (var i = 1; i < map.length; i++) { if (map[i].width > widest.width) widest = map[i]; }
For Each
map.forEach(e => { if (e.width > widest.width) widest = e; });
Minified For Loop ES6
for(let t=1;t<map.length;t++)map[t].width>widest.width&&(widest=map[t]);
Minified For Each ES6
map.forEach(d=>{d.width>widest.width&&(widest=d)});
