The JavaScript exception "invalid date" occurs when an invalid date is attempted to be converted to an ISO date string.

Generally speaking, a function is a "subprogram" that can be called by code external (or internal, in the case of recursion) to the function. Like the program itself, a function is composed of a sequence of statements called the function body. Values can be passed to a function as parameters, and the function will return a value.

The rest parameter syntax allows a function to accept an indefinite number of arguments as an array, providing a way to represent variadic functions in JavaScript.

The overflow attribute sets what to do when an element's content is too big to fit in its block formatting context. This feature is not widely implemented yet.

The order attribute indicates the size of the matrix to be used by a <feConvolveMatrix> element.

The points attribute defines a list of points. Each point is defined by a pair of number representing a X and a Y coordinate in the user coordinate system. If the attribute contains an odd number of coordinates, the last one will be ignored.

The seed attribute represents the starting number for the pseudo random number generator of the <feTurbulence> filter primitive.

The transform-origin SVG attribute sets the origin for an item's transformations.

The overline-thickness attribute represents the ideal thickness of the overline. The overline thickness is expressed in the font's coordinate system.

The JavaScript exception "missing } after function body" occurs when there is a syntax mistake when creating a function somewhere. Check if any closing curly braces or parenthesis are in the correct order.
