Jump statements (return, break and continue) and throw expressions move control flow out of the current code block. So any statements that come after a jump are dead code.

Noncompliant Code Example

function fun(a) {
  var i = 10;
  return i + a;
  i++;             // Noncompliant; this is never executed
}

Compliant Solution

function fun(int a) {
  var i = 10;
  return i + a;
}
