Function JSObjectSetPropertyAtIndex

Source 
pub unsafe extern "C" fn JSObjectSetPropertyAtIndex(
    ctx: JSContextRef,
    object: JSObjectRef,
    propertyIndex: c_uint,
    value: JSValueRef,
    exception: *mut JSValueRef,
)
Expand description

Sets a property on an object by numeric index.

  • ctx: The execution context to use.
  • object: The JSObjectRef whose property you want to set.
  • propertyIndex: The property’s name as a number.
  • value: A JSValueRef to use as the property’s value.
  • exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.

Calling JSObjectSetPropertyAtIndex is equivalent to calling JSObjectSetProperty with a string containing propertyIndex, but JSObjectSetPropertyAtIndex provides optimized access to numeric properties.
