I am reading "Javascript : The good Parts" to improve my Javascript bases and knowledge. I was reading stuff about prototype and I encountered in this function :
var stooge = { ... } if(typeof Object.create !== 'function'){ Object.create = function(o) { var F = function () {}; F.prototype = o; return new F(); }; } var another_stooge = Object.create(stooge);
I didn't really get the meaning and the benefit of creating this function.
It's only a shim for the standard Object.create function which isn't available in some browsers (yes, you guessed which one).
Note that it's not complete : it doesn't do everything that is done by Object.create but it's probably enough for the author.
As for why the author wanted to use Object.create instead of a explicit prototype based OOP, it's probably because it's a little simpler.

I am creating an application from legacy code using AngularJS. I wonder what parts of my code should be moved into a directive. For example, iI had thought of moving a table which is used multiple times across the application into a directive. The tables alter from headings and size. Is it worth the effort or even a good practice to turn such things into their own directives or should I create each table in a unique way?
