# babel-plugin-shield A babel plugin to shield your code against annoying undefined property errors (```Uncaught TypeError: Cannot read property 'xyz' of undefined"```). Let's say you have a deep nested object something like this: ```javascript var testObj = { func1: function () { return { b : 2 }; }, testFunc:function(){ var value = this.func2().b; // undefined property func2 } } ``` So as you would have guessed correctly this would through our not so favourite undefined error. till now most of you would have been solving this problem using ```&&``` something like, ```javascript var value = this && this.func2 && this.func2() && this.func2().b; ``` Well, not anymore this plugin is here to **shield** you against all such troubles. ### Getting Started ```javascript $ npm install --save babel-plugin-shield //add shield as plugin in your babelrc { plugins: ['shield'] } ``` ### Usage ```javascript var value = shield_(this.func2().b); ``` That's pretty much it. ### License babel-plugin-shield is released under the [MIT License](http://www.opensource.org/licenses/MIT) ### Thanks
