The value that is returned from a call to a function is the value of that function call. For example, with that function we can set a variable to the value that is returned using the following code (which would set result to 5). var result = num(3,3); The difference between functions and other variables is that the function has to be run in order to determine its value.

Stereolithography (SL) is one of several methods used to create 3D-printed objects. It's the process by which a uniquely designed 3D printing machine, called a stereolithograph apparatus (SLA) converts liquid plastic into solid objects. The process was patented as a means of rapid prototyping in 1986 by Charles Hull, co-founder of 3D Systems, Inc., a leader in the 3D printing industry.
