Javascript Question

I came across the following line

`hsb.s = max != 0 ? 255 * delta / max : 0;`

What do the

`?`

`:`

Answer

It is called the Conditional Operator (which is a ternary operator).

It has the form of: `condition`

? `value-if-true`

: `value-if-false`

Think of the `?`

as "then" and `:`

as "else".

Your code is equivalent to

```
if (max != 0)
hsb.s = 255 * delta / max;
else
hsb.s = 0;
```
