Method definition is a shorter syntax for defining a function property in an object initializer. It can also be used in classes.

The <use> element takes nodes from within the SVG document, and duplicates them somewhere else. The effect is the same as if the nodes were deeply cloned into a non-exposed DOM, then pasted where the use element is, much like cloned template elements.

The clip-path presentation attribute defines or associates a clipping path with the element it is related to.

The right shift assignment (>>=) operator performs right shift on the two operands and assigns the result to the left operand.

The right shift (>>) operator returns a number or BigInt whose binary representation is the first operand shifted by the specified number of bits to the right. Excess bits shifted off to the right are discarded, and copies of the leftmost bit are shifted in from the left. This operation is also called "sign-propagating right shift" or "arithmetic right shift", because the sign of the resulting number is the same as the sign of the first operand.

Below, you'll find a list of errors which are thrown by JavaScript. These errors can be a helpful debugging aid, but the reported problem isn't always immediately clear. The pages below will provide additional details about these errors. Each error is an object based upon the Error object, and has a name and a message.

The import() syntax, commonly called dynamic import, is a function-like expression that allows loading an ECMAScript module asynchronously and dynamically into a potentially non-module environment.

The increment (++) operator increments (adds one to) its operand and returns the value before or after the increment, depending on where the operator is placed.

The extends keyword is used in class declarations or class expressions to create a class that is a child of another class.
