  • The introduction of strict mode aims to avoid common coding problems in ECMAScript applications. This is achieved with the presence of a lone string literal in a unit (script or function): "use strict;"
  • for either the entire script (if at the top of the script) or for a single function (if the first part of a function).
  • var i=3 is needed
  • ...10 more annotations...
  • and introducing new variables through eval cannot occu
  • delete cannot be used against arguments, functions or variables or other properties with the configurable flag set to false
  • with statements, often a source of errors, are no longer used and considered syntax errors
  • Functions can no longer have duplicate arguments with the same name Objects can no longer have duplicate properties with the same name
  • Access to the global object becomes a runtime error
  • A new JSON object with parse and stringify to support efficient generation of JSON data; like eval but without the security implications of being able to reduce code
  • Array now has standard functions, such as indexOf(), map(), filter(), and reduce()
  • Object now has seal()
  • and freeze()
  • Object.getPrototypeof() returns the prototype of the given object

  • Closure Compiler is a JavaScript optimizer that compiles web apps down into compact, high-performance JavaScript code.
  • Closure Library is a broad, well-tested, modular, and cross-browser JavaScript library. Web developers can pull just what they need from a wide set of reusable UI widgets and controls, as well as lower-level utilities for the DOM, server communication, animation, data structures, unit testing, rich-text editing, and much, much more. (Seriously. Check the docs.)
  • Closure Templates grew out of a desire for web templates that are precompiled to efficient JavaScript.  Closure Templates have a simple syntax that is natural for programmers.
