The <feBlend> SVG filter primitive composes two objects together ruled by a certain blending mode. This is similar to what is known from image editing software when blending two layers. The mode is defined by the mode attribute.

The Object.setPrototypeOf() static method sets the prototype (i.e., the internal [[Prototype]] property) of a specified object to another object or null.

Assertions include boundaries, which indicate the beginnings and endings of lines and words, and other patterns indicating in some way that a match is possible (including look-ahead, look-behind, and conditional expressions).

The Object.getOwnPropertyNames() static method returns an array of all properties (including non-enumerable properties except for those which use Symbol) found directly in a given object.

The <feMerge> SVG element allows filter effects to be applied concurrently instead of sequentially. This is achieved by other filters storing their output via the result attribute and then accessing it in a <feMergeNode> child.

The bitwise XOR (^) operator returns a number or BigInt whose binary representation has a 1 in each bit position for which the corresponding bits of either but not both operands are 1.

The bbox attribute defines the maximal bounding box of a font.

BigInt values represent numeric values which are too large to be represented by the number primitive.

The SVG <text> element draws a graphics element consisting of text. It's possible to apply a gradient, pattern, clipping path, mask, or filter to <text>, like any other SVG graphics element.

The greater than or equal (>=) operator returns true if the left operand is greater than or equal to the right operand, and false otherwise.
