Enum boa_engine::builtins::function::ThisMode
source · pub enum ThisMode {
Lexical,
Strict,
Global,
}
Expand description
Represents the [[ThisMode]]
internal slot of function objects.
More information:
Variants§
Lexical
The this
value refers to the this
value of a lexically enclosing function.
Strict
The this
value is used exactly as provided by an invocation of the function.
Global
The this
value of undefined
or null
is interpreted as a reference to the global object,
and any other this
value is first passed to ToObject
.
