 <p>Each key in the object literal (for example, <code>friction</code>) serves as a unique identifier, and its value (<code>0.5</code>) is the data associated with that key. You can think of an object literal as a simple dictionary or lookup table—in this case, holding the desired settings for a new Matter.js body. Note, however, that while the <code>options</code> argument is useful for configuring the body, other initial conditions, such as linear or angular velocity, can be set via static methods of the <code>Matter.Body</code> class:</p>

 <p>Imagine that the moment you click the mouse over a shape, the mouse attaches to that body with a string. Now you can move the mouse around, and it will drag the body around with it until you release the mouse. This works in a similar fashion as a revolute joint in that you can set the length of that “string” to 0, effectively moving a shape with the mouse.</p>
