Strict Mode

It catches some common coding bloopers, throwing exceptions.

It prevents, or throws errors, when relatively ?unsafe? actions are taken (such as gaining access to the global object).

It disables features that are confusing or poorly thought out.

Example


function imStrict(){
  "use strict";
  // ... your code ...
}
