The TypeError object represents an error when an operation could not be performed, typically (but not exclusively) when a value is not of the expected type.

The Uint16Array typed array represents an array of 16-bit unsigned integers in the platform byte order. If control over byte order is needed, use DataView instead. 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).

The patternContentUnits attribute indicates which coordinate system to use for the contents of the <pattern> element.

The gradientUnits attribute defines the coordinate system used for attributes specified on the gradient elements.

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 k4 attribute defines one of the values to be used within the arithmetic operation of the <feComposite> filter primitive.

The SharedArrayBuffer object is used to represent a generic raw binary data buffer, similar to the ArrayBuffer object, but in a way that they can be used to create views on shared memory. A SharedArrayBuffer is not a Transferable Object, unlike an ArrayBuffer which is transferable.

The String object is used to represent and manipulate a sequence of characters.

The <mask> SVG element defines an alpha mask for compositing the current object into the background. A mask is used/referenced using the mask property.

The baseFrequency attribute represents the base frequency parameter for the noise function of the <feTurbulence> filter primitive.
