javascript - CoffeeScript中的三元操作(Ternary operation in CoffeeScript)

Question

I need to set value to a that depends on a condition.(我需要设置值， a是取决于一个条件。)

What is the shortest way to do this with CoffeeScript?(使用CoffeeScript执行此操作的最短方法是什么？)

Eg this is how I'd do it in JavaScript:(这就是我在JavaScript中的表现：)

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

Answer 1

Since everything is an expression, and thus results in a value, you can just use if/else .(由于一切都是表达式，因此产生一个值，你可以使用if/else 。)

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