The name data property of a Function instance indicates the function's name as specified when it was created, or it may be either anonymous or '' (an empty string) for functions created anonymously.

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 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.

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

When SVG was specified, support for web fonts was not widespread in browsers. Since accessing the correct font file is, however, crucial for rendering text correctly, a font description technology was added to SVG to provide this ability. It was not meant for compatibility with other formats like PostScript or OTF, but rather as a simple means of embedding glyph information into SVG when rendered.

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

The parseFloat() function parses a string argument and returns a floating point number.

The <polyline> SVG element is an SVG basic shape that creates straight lines connecting several points. Typically a polyline is used to create open shapes as the last point doesn't have to be connected to the first point. For closed shapes see the <polygon> element.

The Proxy object enables you to create a proxy for another object, which can intercept and redefine fundamental operations for that object.

The encodeURI() function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two surrogate characters). Compared to encodeURIComponent(), this function encodes fewer characters, preserving those that are part of the URI syntax.
