 @category
 @discussion Instances of JSValue implement the following methods in order to enable
 support for subscript access by key and index, for example:

 @textblock
 JSValue *objectA, *objectB;
 JSValue *v1 = object[@"X"]; // Get value for property "X" from 'object'.
 JSValue *v2 = object[42];   // Get value for index 42 from 'object'.
 object[@"Y"] = v1;          // Assign 'v1' to property "Y" of 'object'.
 object[101] = v2;           // Assign 'v2' to index 101 of 'object'.
 @/textblock

 An object key passed as a subscript will be converted to a JavaScript value,
 and then the value using the same rules as <code>valueWithObject:inContext:</code>. In macOS
 TBA and iOS TBA and below, the <code>key</code> argument of
 <code>setObject:object forKeyedSubscript:key</code> was restricted to an
 <code>NSString <NSCopying> *</code> but that restriction was never used.
