The SVG conditional processing attributes are all the attributes that can be specified on some SVG elements to control whether or not the element on which it appears should be rendered.

The Intl.NumberFormat() constructor creates Intl.NumberFormat objects.

A <glyph> defines a single glyph in an SVG font.

In programming, inheritance refers to passing down characteristics from a parent to a child so that a new piece of code can reuse and build upon the features of an existing one. JavaScript implements inheritance by using objects. Each object has an internal link to another object called its prototype. That prototype object has a prototype of its own, and so on until an object is reached with null as its prototype. By definition, null has no prototype and acts as the final link in this prototype chain. It is possible to mutate any member of the prototype chain or even swap out the prototype at runtime, so concepts like static dispatching do not exist in JavaScript.

This chapter introduces collections of data which are ordered by an index value. This includes arrays and array-like constructs such as Array objects and TypedArray objects.

JavaScript provides three different value-comparison operations:

Patterns are arguably one of the more confusing fill types to use in SVG. They're also very powerful, so they're worth talking about and getting at least a fundamental grasp on. Like gradients, the <pattern> element should be put in the <defs> section of your SVG file.

This chapter discusses JavaScript's basic grammar, variable declarations, data types and literals.

This chapter introduces collections of data which are indexed by a key; Map and Set objects contain elements which are iterable in the order of insertion.

The decodeURIComponent() function decodes a Uniform Resource Identifier (URI) component previously created by encodeURIComponent() or by a similar routine.
