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.

Now we're ready to start distorting our beautiful images. But first, let's formally introduce the <g> element. With this helper, you can assign properties to a complete set of elements. Actually, that's its only purpose.

The function declaration creates a binding of a new function to a given name.
