RUNJS support coffeescript/less CSS Online editing

Have you noticed that you can now write the script using Coffeescript directly on the RUNJS, using less CSS to write the style.

Let's look at a demo code:

Coffeescript:

# Assignment:

Number = 42

opposite = True

# Conditions:

Number = -42 if opposite

# functions:

Square = (x)-> x * x

# Arrays:

list = [1, 2, 3, 4, 5]

# Objects:

Math =

Root:Math.sqrt

Square:square

Cube: (x)-> x * square x

# Splats:

Race = (Winner, runners ....) )->

Print winner, runners

# existence:

Alert "I knew it!" if Elvis?

# Array Comprehensions:

cubes = (math.cube num for num in list)

document.write "Result:" + cubes

Less:

@bgcolor: #CCC;

body{

Background-color: @bgcolor;

}
