Fibonacci PowerShell Example

He presents a Fibonacci example and demonstrates multiple assignment for variables.

In this PowerShell example, the second line sets the variables a and b to 0 and 1. Then again in the sixth line. Notice that the expression ($a+$b) is evaluated and then assigned.

Function Fibonacci($n=10) {
    $a, $b = 0, 1            

    while($b -lt $n) {
        $b
        $a, $b = $b, ($a+$b)
    }
}
