DOMString
A DOMString
is a sequence of 16-bit unsigned integers, typically interpreted as UTF-16 code units. This corresponds exactly to the JavaScript primitive String type. When a DOMString
is provided to JavaScript, it maps directly to the corresponding String
.
When a Web API accepts a DOMString
, the value provided will be stringified, using the ToString
abstract operation. (For types other than Symbol, this has the same behavior as the String()
function.)
Certain Web APIs accepting a DOMString
have an additional legacy behavior, where passing null
stringifies to the empty string instead of the usual "null"
.
