This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
HTMLElement.outerText is a nonstandard property. As a getter, it returns the same value as
Node.innerText. As a setter, it removes the current node and replaces it with the given text.
Not part of any specification. Standards discussion: whatwg/html#668.
Microsoft has a description on MSDN.
