The set syntax binds an object property to a function to be called when there is an attempt to set that property. It can also be used in classes.

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.

The <switch> SVG element evaluates any requiredFeatures, requiredExtensions and systemLanguage attributes on its direct child elements in order, and then renders the first child where these attributes evaluate to true.

The cx attribute defines the x-axis coordinate of a center point.

The attributeName attribute indicates the name of the CSS property or attribute of the target element that is going to be changed during an animation.

The constructor method is a special method of a class for creating and initializing an object instance of that class.

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 accent-height attribute defines the distance from the origin to the top of accent characters, measured by a distance within the font coordinate system.

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.
