The execution order of return in JS' try catch finally

Situation 1 ：

finally There is return =》 Only finally Of return take effect .

let a = 1;
let b = 0;

function test() {
    
  try {
    
    let c = a / b;
    return c;
  } catch (error) {
    
    return "error";
  } finally {
    
    return "finally";
  }
}
console.log(test()); // finally

function test2() {
    
  try {
    
    let c = a / b;
    d++;
    return c;
  } catch (error) {
    
    return "error";
  } finally {
    
    return "finally";
  }
}
console.log(test2()); // finally

Situation two ：

finally No, return =》 Will execute first finally Code for , And then execute try or catch Medium return.

function test4() {
    
  try {
    
    let c = a / b;
    return c;
  } catch (error) {
    
    return "error";
  } finally {
    
    console.log("finally...");
  }
}
console.log(test4());
// finally...
// Infinity

function test3() {
    
  try {
    
    let c = a / b;
    d++;
    return c;
  } catch (error) {
    
    return "error";
  } finally {
    
    console.log("finally...");
  }
}
console.log(test3());
// finally...
// error

function test5() {
    
  try {
    
    if (b == 0) {
    
      return "b";
    }
    let c = a / b;
    return c;
  } catch (error) {
    
    return "error";
  } finally {
    
    console.log("finally...");
  }
}
console.log(test5());
// finally...
// b
