What does the program print?

JavaScript

let s = "";
try {
    s += "a";
    throw new Error("x");
    s += "b";
} catch (e) {
    s += "c";
}
s += "d";
console.log(s);

acd

Expecting abcd: throw stops the try block at once, so s += "b" never runs and the program jumps straight into catch.
Expecting the program to stop after catch: once the error is caught, the code after the whole try…catch keeps running, so "d" is added.
