The multiplication assignment (*=) operator performs multiplication on the two operands and assigns the result to the left operand.

The 64-bit signed integer type.

The spacing attribute indicates how the user agent should determine the spacing between typographic characters that are to be rendered along a path.

The bitwise AND assignment (&=) operator performs bitwise AND on the two operands and assigns the result to the left operand.

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 divisor attribute specifies the value by which the resulting number of applying the kernelMatrix of a <feConvolveMatrix> element to the input image color value is divided to yield the destination color value.

The function declaration creates a binding of a new function to a given name.

The dy attribute indicates a shift along the y-axis on the position of an element or its content.

The async function declaration creates a binding of a new async function to a given name. The await keyword is permitted within the function body, enabling asynchronous, promise-based behavior to be written in a cleaner style and avoiding the need to explicitly configure promise chains.

The spread (...) syntax allows an iterable, such as an array or string, to be expanded in places where zero or more arguments (for function calls) or elements (for array literals) are expected. In an object literal, the spread syntax enumerates the properties of an object and adds the key-value pairs to the object being created.
