if is an expression

No ternary here — you don’t need one, because if already returns a value.

fix age = 20;
fix label = if (age >= 18) { "adult" } else { "minor" };
label

Chain more conditions with else if, the one bit of control-flow sugar Ascent allows:

fix score = 75;
if (score >= 90) { "A" } else if (score >= 70) { "B" } else { "C" }

Two rules to keep in mind: braces are mandatory even for a single-line branch, and both branches have to produce the same type — you can’t hand back a String from one side and an Int from the other.

Your turn: write your own if/else if/else, bind it to a fix slot, and print which branch got picked.
