Finally overrides any return statement from the try/catch.

We write try/catch/finally for error handling in Javascript -

function tryTryTry() {
  try {
    return 4;
  } catch (e) {
    console.log(e);
  } finally {
    return 42;
  }
}
console.log(tryTryTry());
//42

The function returns 42 and not 4.

Why? Because finally always gets executed - both for the normal execution flow and errors. In the above code block -

try returns 4
control flow jumps to finally block
finally returns 42
caller gets 42
