The crossorigin attribute, valid on the <image>, <feImage>, and <script> elements, provides support for configuration of Cross-Origin Resource Sharing (CORS) requests for the element's fetched data.

The <ellipse> SVG element is an SVG basic shape, used to create ellipses based on a center coordinate, and both their x and y radius.

A literal character specifies exactly itself to be matched in the input text.

The startOffset attribute defines an offset from the start of the path for the initial current text position along the path after converting the path to the <textPath> element's coordinate system.

The BigUint64Array typed array represents an array of 64-bit unsigned integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0n 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 JavaScript exception "too much recursion" or "Maximum call stack size exceeded" occurs when there are too many function calls, or a function is missing a base case.

The equality (==) operator checks whether its two operands are equal, returning a Boolean result. Unlike the strict equality operator, it attempts to convert and compare operands that are of different types.

The JavaScript exception "missing = in const declaration" occurs when a const declaration was not given a value in the same statement (like const RED_FLAG;). You need to provide one (const RED_FLAG = true).

The style attribute allows to style an element using CSS declarations. It functions identically to the style attribute in HTML.
