Javascript Question

Ternary operation in CoffeeScript

I need to set value to

a
that depends on a condition.

What is the shortest way to do this with CoffeeScript?

E.g. this is how I'd do it in JavaScript:

a = true ? 5 : 10 # => a = 5
a = false ? 5 : 10 # => a = 10

Answer

Since everything is an expression, and thus results in a value, you can just use if/else.

a = if true then 5 else 10
a = if false then 5 else 10
