The JavaScript exception "property name __proto__ appears more than once in object literal" occurs when an object literal contains multiple occurrences of the __proto__ field, which is used to set the prototype of this new object.

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

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 crossorigin attribute, valid on the <image> and <feImage> elements, provides support for configuration of the Cross-Origin Resource Sharing (CORS) requests for the element's fetched data.

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 patternUnits attribute indicates which coordinate system to use for the geometry properties of the <pattern> element.

The JavaScript exception "octal escape sequences can't be used in untagged template literals or in strict mode code" occurs when octal escape sequences are used in strict mode string literals or untagged template literals.

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 Uint8Array typed array represents an array of 8-bit unsigned integers. The contents are initialized to 0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).
