The SVG conditional processing attributes are all the attributes that can be specified on some SVG elements to control whether or not the element on which it appears should be rendered.

The numOctaves attribute defines the number of octaves for the noise function of the <feTurbulence> primitive.

The for...of statement executes a loop that operates on a sequence of values sourced from an iterable object. Iterable objects include instances of built-ins such as Array, String, TypedArray, Map, Set, NodeList (and other DOM collections), as well as the arguments object, generators produced by generator functions, and user-defined iterables.

The preserveAspectRatio attribute indicates how an element with a viewBox providing a given aspect ratio must fit into a viewport with a different aspect ratio.

The fx attribute defines the x-axis coordinate of the focal point for a radial gradient.

Generally speaking, a function is a "subprogram" that can be called by code external (or internal, in the case of recursion) to the function. Like the program itself, a function is composed of a sequence of statements called the function body. Values can be passed to a function as parameters, and the function will return a value.

The order attribute indicates the size of the matrix to be used by a <feConvolveMatrix> element.

The with statement extends the scope chain for a statement.

The flood-color attribute indicates what color to use to flood the current filter primitive subregion.

The division assignment (/=) operator performs division on the two operands and assigns the result to the left operand.
