The static import declaration is used to import read-only live bindings which are exported by another module. The imported bindings are called live bindings because they are updated by the module that exported the binding, but cannot be re-assigned by the importing module.

The Uint32Array typed array represents an array of 32-bit unsigned integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

The Int8Array typed array represents an array of 8-bit signed integers. The contents are initialized to 0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

A backreference refers to the submatch of a previous capturing group and matches the same text as that group. For named capturing groups, you may prefer to use the named backreference syntax.

The Promise object represents the eventual completion (or failure) of an asynchronous operation and its resulting value.

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

The maskContentUnits attribute indicates which coordinate system to use for the contents of the <mask> element.

The Map object holds key-value pairs and remembers the original insertion order of the keys. Any value (both objects and primitive values) may be used as either a key or a value.

The pointer-events attribute is a presentation attribute that allows defining whether or when an element may be the target of a mouse event.

The origin attribute specifies the origin of motion for an animation. It has no effect in SVG.
