The u1 attribute specifies list of Unicode characters (refer to the description of the unicode attribute of the <glyph> element for a description of how to express individual Unicode characters) and/or ranges of Unicode characters, which identify a set of possible first glyph in a kerning pair.

The unicode-range attribute defines the range of ISO 10646 characters possibly covered by the glyphs in a font.

The xlink:show attribute indicates how a linked resource should be opened and is meant for XLink-aware processors. In case of a conflict, the target attribute has priority, since it can express a wider range of values.

The Intl.PluralRules object enables plural-sensitive formatting and plural-related language rules.

The x1 attribute is used to specify the first x-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the x attribute instead.

The Object.freeze() static method freezes an object. Freezing an object prevents extensions and makes existing properties non-writable and non-configurable. A frozen object can no longer be changed: new properties cannot be added, existing properties cannot be removed, their enumerability, configurability, writability, or value cannot be changed, and the object's prototype cannot be re-assigned. freeze() returns the same object that was passed in.

This chapter describes JavaScript's expressions and operators, including assignment, comparison, arithmetic, bitwise, logical, string, ternary and more.

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.

This guide gives you all you need to get started with JavaScript module syntax.

Let us dive straight in with a simple example. Take a look at the following code.
