Semi-Colon Hell Javascript

semi-colon.js

/**
  Here, the parser will add a semi colon after return causing the function to return nothing.
**/
function test(){
  var name = "Hello";
  return // it will add a ; here
  {
    name: name
  }
}

/**
  This one is even weirder.....
  It does't add it in the case of a leading parenthesis
  You end up with a type error since is assumes "console.log()" is a function and (someList || []) is its parameter
**/

function test2(){
  var someList = undefined
  
  console.log("Hi!") // does not add it here!
  (someList || []).map((item) => item) 
}
