# operator [] method

E operator [] (dynamic index)
override

Returns the value associated with `property` from the proxied JavaScript object.

The type of `property` must be either String or num.

## Implementation

    E operator [](dynamic index) {
      // TODO(justinfagnani): fix the semantics for non-ints
      // dartbug.com/14605
      if (index is num && index == index.toInt()) {
        _checkIndex(index);
      }
      return super[index];
    }
