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

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

SVG is an XML language, similar to XHTML, which can be used to draw vector graphics, such as the one shown below. It can be used to create an image either by specifying all the lines and shapes necessary, by modifying already existing raster images, or by a combination of both. The image and its components can also be transformed, composited together, or filtered to change their appearance completely.

The Proxy and Reflect objects allow you to intercept and define custom behavior for fundamental language operations (e.g., property lookup, assignment, enumeration, function invocation, etc.). With the help of these two objects you are able to program at the meta level of JavaScript.

SVG supports multiple ways to specify fonts for <text> elements. The recommended modern approach is to use CSS, in much the same way as you would style fonts in HTML.

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 <missing-glyph> SVG element's content is rendered, if for a given character the font doesn't define an appropriate <glyph>.

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.

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 <pattern> SVG element defines a graphics object which can be redrawn at repeated x- and y-coordinate intervals ("tiled") to cover an area.
