The path attribute has two different meanings, either it defines a text path along which the characters of a text are rendered, or a motion path along which a referenced element is animated.

The null keyword refers to the null primitive value, which represents the intentional absence of any object value.

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 dx attribute indicates a shift along the x-axis on the position of an element or its content.

The media attribute specifies a media query that must be matched for a style sheet to apply.

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

The await using declaration declares block-scoped local variables that are asynchronously disposed. Like const, variables declared with await using must be initialized and cannot be reassigned. The variable's value must be either null, undefined, or an object with a [Symbol.asyncDispose]() or [Symbol.dispose]() method. When the variable goes out of scope, the [Symbol.asyncDispose]() or [Symbol.dispose]() method of the object is called and awaited, to ensure that resources are freed.

The min attribute specifies the minimum value of the active animation duration.

The class declaration creates a binding of a new class to a given name.

The intercept attribute defines the intercept of the linear function of color component transfers when the type attribute is set to linear.
