Sometimes you have to secure a method with a condition. But you also get one more indentation space. Is it okay to use something like in the second case? less secure or safe maybe? just asking

indentation.js

// Whats Better?

// more indentation
function myFunction(data){
  if(data){
    // do some important stuff
    data.parse()
  }
}

// or (lee identation)
function myFunction(data){
  if(!data){ return false; }

  // do some important stuff
  data.parse();

}
