The JavaScript exception "illegal character" occurs when the lexer reads a character that's not part of a string literal, and the character cannot constitute a valid token in the language.

A literal character specifies exactly itself to be matched in the input text.

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.

The y1 attribute is used to specify the first y-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the y attribute instead.

The async function* keywords can be used to define an async generator function inside an expression.

The xlink:href attribute defines a reference to a resource as a reference IRI. The exact meaning of that link depends on the context of each element using it.

The nullish coalescing assignment (??=) operator, also known as the logical nullish assignment operator, only evaluates the right operand and assigns to the left if the left operand is nullish (null or undefined).

The xlink:show attribute indicates how a linked resource should be opened and is meant for XLink-aware processors. In case of a conflict, the target attribute has priority, since it can express a wider range of values.

Private elements are counterparts of the regular class elements which are public, including class fields, class methods, etc. Private elements get created by using a hash # prefix and cannot be legally referenced outside of the class. The privacy encapsulation of these class elements is enforced by JavaScript itself. The only way to access a private element is via dot notation, and you can only do so within the class that defines the private element.
