The <polygon> element defines a closed shape consisting of a set of connected straight line segments. The last point is connected to the first point.

The feMergeNode takes the result of another filter to be processed by its parent <feMerge>.

The parseInt() function parses a string argument and returns an integer of the specified radix (the base in mathematical numeral systems).

The <feTurbulence> SVG filter primitive creates an image using the Perlin turbulence function. It allows the synthesis of artificial textures like clouds or marble. The resulting image will fill the entire filter primitive subregion.

The <feSpecularLighting> SVG filter primitive lights a source graphic using the alpha channel as a bump map. The resulting image is an RGBA image based on the light color. The lighting calculation follows the standard specular component of the Phong lighting model. The resulting image depends on the light color, light position and surface geometry of the input bump map. The result of the lighting calculation is added. The filter primitive assumes that the viewer is at infinity in the z direction.

Operator precedence determines how operators are parsed concerning each other. Operators with higher precedence become the operands of operators with lower precedence.

The <view> SVG element defines a particular view of an SVG document. A specific view can be displayed by referencing the <view> element's id as the target fragment of a URL.

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

The <feFlood> SVG filter primitive fills the filter subregion with the color and opacity defined by flood-color and flood-opacity.

The <feTile> SVG filter primitive allows to fill a target rectangle with a repeated, tiled pattern of an input image. The effect is similar to the one of a <pattern>.
