The z attribute defines the location along the z-axis for a light source in the coordinate system established by the primitiveUnits attribute on the <filter> element, assuming that, in the initial coordinate system, the positive z-axis comes out towards the person viewing the content and assuming that one unit along the z-axis equals one unit in x and y.

The bitwise XOR (^) operator returns a number or BigInt whose binary representation has a 1 in each bit position for which the corresponding bits of either but not both operands are 1.

The parseFloat() function parses a string argument and returns a floating point number.

The JavaScript exception "missing formal parameter" occurs when your function declaration is missing valid parameters.

The Uint32Array typed array represents an array of 32-bit unsigned integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

The xChannelSelector attribute indicates which color channel from in2 to use to displace the pixels in in along the x-axis.

The JavaScript exception "missing ] after element list" occurs when there is an error with the array initializer syntax somewhere. Likely there is a closing square bracket (]) or a comma (,) missing.

The JavaScript exception "incomplete quantifier in regular expression" occurs when a regular expression pattern contains a {, but it does not start a valid quantifier.

The pointer-events attribute is a presentation attribute that allows defining whether or when an element may be the target of a mouse event.

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