The k1 attribute defines one of the values to be used within the arithmetic operation of the <feComposite> filter primitive.

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 new.target meta-property lets you detect whether a function or constructor was called using the new operator. In constructors and functions invoked using the new operator, new.target returns a reference to the constructor or function that new was called upon. In normal function calls, new.target is undefined.

Utilities for the slice primitive type.

The InternalError object indicates an error that occurred internally in the JavaScript engine.

Redundant constants module for the `i32` primitive type.

The isFinite() function determines whether a value is finite, first converting the value to a number if necessary. A finite number is one that's not NaN or ±Infinity. Because coercion inside the isFinite() function can be surprising, you may prefer to use Number.isFinite().

The rx attribute defines a radius on the x-axis.

Number values represent floating-point numbers like 37 or -9.25.

The Float16Array typed array represents an array of 16-bit floating point numbers 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).
