The JavaScript exception "invalid class set operation in regular expression" occurs when a double punctuator sequence appears in a v-mode character class but it is not recognized by the syntax.

A character escape represents a character that may not be able to be conveniently represented in its literal form.

The unsigned right shift (>>>) operator returns a number whose binary representation is the first operand shifted by the specified number of bits to the right. Excess bits shifted off to the right are discarded, and zero bits are shifted in from the left. This operation is also called "zero-filling right shift", because the sign bit becomes 0, so the resulting number is always positive. Unsigned right shift does not accept BigInt values.

The yield* operator can be used within generator (sync or async) functions to delegate to another iterable object, such as a Generator. Inside async generator functions, it can additionally be used to delegate to another async iterable object, such as an AsyncGenerator.

An error returned by `BufWriter::into_inner` which combines an error that happened while writing out the buffer, and the buffered writer object which may be used to recover from the condition.
