Should I 'use strict' for every single javascript function I write?

Question

Should I \'use strict\' for every single javascript function I write?

What is a good practice to use strict in a large AngularJS project? Using it globally can break

Answer 1

Short answer, yes! You don't need to include it for every function, but rather you can just add it once per JavaScript file. When you start the file, start with a closure like this:

(function () {
  "use strict";
  // Rest of your code.

})();
