title: Why was block scope not originally implemented in JavaScript?
body: <p>I have read, and discovered through my own experience, that JavaScript doesn't have a block scope. Assuming that the language was designed this way for a reason, can you explain to me what is that reason? </p>
  
  <p>I've looked around on Google and here, but the posts I have found just reiterate that JS has a function scope and not block scope, without explaining why. I'm curious to know why this is actually the case.</p>
