The bitwise OR (|) operator returns a number or BigInt whose binary representation has a 1 in each bit position for which the corresponding bits of either or both operands are 1.

The <image> SVG element includes images inside SVG documents. It can display raster image files or other SVG files.

The bitwise OR assignment (|=) operator performs bitwise OR on the two operands and assigns the result to the left operand.

The <g> SVG element is a container used to group other SVG elements.

The eval() function evaluates JavaScript code represented as a string and returns its completion value. The source is parsed as a script.

The <feDiffuseLighting> SVG filter primitive lights an image using the alpha channel as a bump map. The resulting image, which is an RGBA opaque image, depends on the light color, light position and surface geometry of the input bump map.

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

The bitwise AND assignment (&=) operator performs bitwise AND on the two operands and assigns the result to the left operand.

The <fePointLight> filter primitive defines a light source which allows to create a point light effect. It that can be used within a lighting filter primitive: <feDiffuseLighting> or <feSpecularLighting>.

Regular expressions are patterns used to match character combinations in strings. In JavaScript, regular expressions are also objects. These patterns are used with the exec() and test() methods of RegExp, and with the match(), matchAll(), replace(), replaceAll(), search(), and split() methods of String. This chapter describes JavaScript regular expressions.
