Expand description

Define a property on obj.

This function uses JS::ObjectOpResult to indicate conditions that ES6 specifies as non-error failures. This is inconvenient at best, so use this function only if you are implementing a proxy handler’s defineProperty() method. For all other purposes, use one of the many DefineProperty functions below that throw an exception in all failure cases.

Implements: ES6 [[DefineOwnProperty]] internal method.
