The __defineGetter__() method of Object instances binds an object's property to a function to be called when that property is looked up.

The hasOwnProperty() method of Object instances returns a boolean indicating whether this object has the specified property as its own property (as opposed to inheriting it).

SVG images can be used as an image format, in a number of contexts. Browsers support SVG images in:

The Object.values() static method returns an array of a given object's own enumerable string-keyed property values.

The Object.entries() static method returns an array of a given object's own enumerable string-keyed property key-value pairs.

The Function() constructor creates Function objects. Calling the constructor directly can create functions dynamically, but suffers from security and similar (but far less significant) performance issues as eval(). However, unlike eval (which may have access to the local scope), the Function constructor creates functions which execute in the global scope only.

The to attribute indicates the final value of the attribute that will be modified during the animation.

The x attribute defines an x-axis coordinate in the user coordinate system.

SVG elements can be modified using attributes that specify details about exactly how the element should be handled or rendered.

The toString() method of TypedArray instances returns a string representing the specified typed array and its elements. This method has the same algorithm as Array.prototype.toString().
