The color-interpolation attribute specifies the color space for gradient interpolations, color animations, and alpha compositing.

The color-interpolation-filters attribute specifies the color space for imaging operations performed via filter effects.

The baseline-shift attribute allows repositioning of the dominant-baseline relative to the dominant-baseline of the parent text content element. The shifted object might be a sub- or superscript.

The <linearGradient> SVG element lets authors define linear gradients to apply to other SVG elements.

The for...of statement executes a loop that operates on a sequence of values sourced from an iterable object. Iterable objects include instances of built-ins such as Array, String, TypedArray, Map, Set, NodeList (and other DOM collections), as well as the arguments object, generators produced by generator functions, and user-defined iterables.

The NaN global property is a value representing Not-A-Number.

The bitwise AND (&) operator returns a number or BigInt whose binary representation has a 1 in each bit position for which the corresponding bits of both operands are 1.

The bitwise NOT (~) operator returns a number or BigInt whose binary representation has a 1 in each bit position for which the corresponding bit of the operand is 0, and a 0 otherwise.

The BigInt64Array typed array represents an array of 64-bit signed integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0n 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).

Generally speaking, a function is a "subprogram" that can be called by code external (or internal, in the case of recursion) to the function. Like the program itself, a function is composed of a sequence of statements called the function body. Values can be passed to a function as parameters, and the function will return a value.
