## JavaScript like Destructuring using Structured Binding in C++

### Binding by value:
```cpp
pair<int, int> cur = {1, 2};
auto [x, y] = cur;
Expand All @@ -36,8 +38,22 @@ auto [x, y] = cur;
array<int, 3> arr = {1, 0, -1};
auto [a, b, c] = arr;
// a is now 1, b is now 0, c is now -1
a++;
// a is now 2. arr[0] is unaffected, remains 1.
```

### Binding by reference:
```cpp
array<int, 3> arr = {1, 0, -1};
auto& [a, b, c] = arr;
// a is now 1, b is now 0, c is now -1
a++;
// a is now 2, arr[0] is also 2.
```

**Note:** Structured binding cannot be done with vectors since vectors are dynamic.
