SVG elements can be modified using attributes that specify details about exactly how the element should be handled or rendered.

JavaScript applications consist of statements with an appropriate syntax. A single statement may span multiple lines. Multiple statements may occur on a single line if each statement is separated by a semicolon. This isn't a keyword, but a group of keywords.

A WeakMap is a collection of key/value pairs whose keys must be objects or non-registered symbols, with values of any arbitrary JavaScript type, and which does not create strong references to its keys. That is, an object's presence as a key in a WeakMap does not prevent the object from being garbage collected. Once an object used as a key has been collected, its corresponding values in any WeakMap become candidates for garbage collection as well — as long as they aren't strongly referred to elsewhere. The only primitive type that can be used as a WeakMap key is symbol — more specifically, non-registered symbols — because non-registered symbols are guaranteed to be unique and cannot be re-created.

The <feBlend> SVG filter primitive composes two objects together ruled by a certain blending mode. This is similar to what is known from image editing software when blending two layers. The mode is defined by the mode attribute.

When talking about text in SVG, we have to differentiate between two almost completely separate topics. One is the inclusion and display of text in an image, and the other is SVG fonts. The latter is described in a later section of the tutorial, while this page will focus on the first part: bringing text into an SVG image.

The <feColorMatrix> SVG filter element changes colors based on a transformation matrix. Every pixel's color value [R,G,B,A] is matrix multiplied by a 5 by 5 color matrix to create new color [R',G',B',A'].

The <feFuncR> SVG filter primitive defines the transfer function for the red component of the input graphic of its parent <feComponentTransfer> element.

The [Symbol.iterator]() method of arguments objects implements the iterable protocol and allows arguments objects to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns an array iterator object that yields the value of each index in the arguments object.
