The nullish coalescing assignment (??=) operator, also known as the logical nullish assignment operator, only evaluates the right operand and assigns to the left if the left operand is nullish (null or undefined).

The inequality (!=) operator checks whether its two operands are not equal, returning a Boolean result. Unlike the strict inequality operator, it attempts to convert and compare operands that are of different types.

The instanceof operator tests to see if the prototype property of a constructor appears anywhere in the prototype chain of an object. The return value is a boolean value. Its behavior can be customized with Symbol.hasInstance.

The <pattern> element defines a graphics object which can be redrawn at repeated x- and y-coordinate intervals ("tiled") to cover an area.

The textual content for a <text> SVG element can be either character data directly embedded within the <text> element or the character data content of a referenced element, where the referencing is specified with a <tref> element.

The arabic-form attribute indicates which of the four possible forms an Arabic glyph represents.

The Uint8Array typed array represents an array of 8-bit unsigned integers. The contents are initialized to 0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

The <marker> element defines a graphic used for drawing arrowheads or polymarkers on a given <path>, <line>, <polyline> or <polygon> element.

The amplitude attribute controls the amplitude of the gamma function of a component transfer element when its type attribute is gamma.
