why are we using bracket notation instead of dot notation in
result = lookup[val];
**Your code so far**
// Setup
function phoneticLookup(val) {
var result = "";
// Only change code below this line
var lookup = {
"alpha": "Adams",
"bravo": "Boston",
"charlie": "Chicago",
"delta": "Denver",
"echo": "Easy",
"foxtrot": "Frank"
}
result = lookup[val];
// Only change code above this line
return result;
}
console.log(phoneticLookup("charlie"));
