The r attribute defines the radius of a circle.

The specularConstant attribute controls the ratio of reflection of the specular lighting. It represents the ks value in the Phong lighting model. The bigger the value the stronger the reflection.

The JavaScript warning "Using //@ to indicate sourceURL pragmas is deprecated. Use //# instead" occurs when there is a deprecated source map syntax in a JavaScript source.

The stop-color attribute indicates what color to use at a gradient stop.

The SharedArrayBuffer() constructor creates SharedArrayBuffer objects.

The fill() method of TypedArray instances changes all elements within a range of indices in a typed array to a static value. It returns the modified typed array. This method has the same algorithm as Array.prototype.fill().

The [@@iterator]() method of TypedArray instances implements the iterable protocol and allows typed arrays to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns an array iterator object that yields the value of each index in the typed array.

The entries() method of TypedArray instances returns a new array iterator object that contains the key/value pairs for each index in the typed array. This method has the same algorithm as Array.prototype.entries().

The findLast() method of TypedArray instances iterates the typed array in reverse order and returns the value of the first element that satisfies the provided testing function. If no elements satisfy the testing function, undefined is returned. This method has the same algorithm as Array.prototype.findLast().

The reverse() method of TypedArray instances reverses a typed array in place and returns the reference to the same typed array, the first typed array element now becoming the last, and the last typed array element becoming the first. In other words, elements order in the typed array will be turned towards the direction opposite to that previously stated. This method has the same algorithm as Array.prototype.reverse().
