Programmer Humor

This, unfortunately, means that semicolons are often inserted in places where you were not expecting them

example:

()=>{
  return {k:"v"}; // returns the object
}
()=>{
  return      // returns undefined 
    {k:"v"};  // unreachable 
}

so the advice is to always include them manually yourself so that you are never unpleasantly surprised.

The example will be unpleasantly surprising, no matter where you put semicolons.
