The escape() function computes a new string in which certain characters have been replaced by hexadecimal escape sequences.

A TypedArray object describes an array-like view of an underlying binary data buffer. There is no global property named TypedArray, nor is there a directly visible TypedArray constructor. Instead, there are a number of different global properties, whose values are typed array constructors for specific element types, listed below. On the following pages you will find common properties and methods that can be used with any typed array containing elements of any type.

The <radialGradient> element lets authors define radial gradients that can be applied to fill or stroke of graphical elements.

The rest parameter syntax allows a function to accept an indefinite number of arguments as an array, providing a way to represent variadic functions in JavaScript.

The filterUnits attribute defines the coordinate system for the attributes x, y, width and height.

The flood-color attribute indicates what color to use to flood the current filter primitive subregion.

The multiplication (*) operator produces the product of the operands.

The ideographic attribute indicates the alignment coordinate for glyphs to achieve ideographic baseline alignment for horizontally oriented glyph layouts. The value is an offset in the font coordinate system.

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 color attribute is used to provide a potential indirect value, currentcolor, for the fill, stroke, stop-color, flood-color, and lighting-color attributes.
