title: Do compilers for javascript differ from web browser to web browser
body: <p>So I am asking does each web browser have there own compiler example IE compiles Javascript from a website and generates sequence A of byte code . </p>
  
  <p>On the other hand, google chrome compiles the same Javascript from the same website and generates sequence B . </p>
  
  <p>I am wondering this because if that is the case would it be beneficial to run the compiler on the Javascript and upload the generated byte code to the website rather than the Javascript itself. And send different byte code based on each browser.</p>
  
  <p>Or are there some other limitations. </p>
