The SVG <animate> element provides a way to animate an attribute of an element over time.

The ArrayBuffer object is used to represent a generic raw binary data buffer.

The <feConvolveMatrix> SVG filter primitive applies a matrix convolution filter effect. A convolution combines pixels in the input image with neighboring pixels to produce a resulting image. A wide variety of imaging operations can be achieved through convolutions, including blurring, edge detection, sharpening, embossing and beveling.

JavaScript is a multi-paradigm, dynamic language with types and operators, standard built-in objects, and methods. Its syntax is based on the Java and C languages — many structures from those languages apply to JavaScript as well. JavaScript supports object-oriented programming with object prototypes and classes. It also supports functional programming since functions are first-class objects that can be easily created via expressions and passed around like any other object.

The <feImage> SVG filter primitive fetches image data from an external source and provides the pixel data as output (meaning if the external source is an SVG image, it is rasterized.)

The <feOffset> SVG filter primitive allows to offset the input image. The input image as a whole is offset by the values specified in the dx and dy attributes.

The font-family attribute indicates which font family will be used to render the text, specified as a prioritized list of font family names and/or generic family names.

The exponentiation (**) operator returns the result of raising the first operand to the power of the second operand. It is equivalent to Math.pow(), except it also accepts BigInts as operands.

The bias attribute shifts the range of the filter. After applying the kernelMatrix of the <feConvolveMatrix> element to the input image to yield a number and applied the divisor attribute, the bias attribute is added to each component. This allows representation of values that would otherwise be clamped to 0 or 1.

The non-standard stack property of an Error instance offers a trace of which functions were called, in what order, from which line and file, and with what arguments. The stack string proceeds from the most recent calls to earlier ones, leading back to the original global scope call.
