Print

Printing allows you to inspect variables on runtime. It works similarly to console.log, only when using print, the output is shown directly within your prototype. Note that you need to use print() in Javascript (but not in CoffeeScript). We will omit these in the rest of the docs.

print "Hello"
# Output: "Hello"

You can inspect any type of value, and even multiple at the same time.
译：您可以检查任何类型的值，甚至同时检查多个类型的值。

layerA = new Layer
    x: 10
    y: 20

# A single property value 
print layerA.x
# Output: 10 

# Multiple values 
print layerA.x, print layerA.y
# Output: 10, 20
