Instance Method Details

#[](i) ⇒ JSI::Base, Object

The instance's subscript value at the given index i. if there is a subschema defined for that index on this JSI's schema, returns the instance's subscript as a JSI instiation of that subschema.

Parameters:

  • i (Integer) —

    the array index to subscript

Returns:

  • (JSI::Base, Object) —

    the instance's subscript value at the given index i. if there is a subschema defined for that index on this JSI's schema, returns the instance's subscript as a JSI instiation of that subschema.

#[]=(i, value) ⇒ Object

assigns the given index of the instance to the given value. if the value is a JSI, its instance is assigned.

Parameters:

  • i (Object) —

    the array index to assign

  • value (Object) —

    the value to be assigned to the given subscript i
