This is first post about Angular.js source code analysis.<\/p>\n

Angular.js start with following code.<\/p>\n

 \r\n  bindJQuery();\r\n  publishExternalAPI(angular);\r\n  jqLite(document).ready(function() {\r\n    angularInit(document, bootstrap);\r\n  });\r\n<\/pre>\n
Before it starts, it will go though some interesting code.<\/p>\n
Angular.js forEach.<\/p>\n
what it to do is assigning value to array.<\/p>\n
 \r\nforEach('multiple,selected,checked,disabled,readOnly,required,open'.split(','), function(value) {\r\n  BOOLEAN_ATTR[lowercase(value)] = value;\r\n});\r\n<\/pre>\n
forEach function is to loop through the list of object.
\nand “Call” anonymous function.<\/strong><\/p>\n
 \r\n function forEach(obj, iterator, context) {\r\n     for(...){\r\n          iterator.call(context,obj[key],key,obj);\r\n     }\r\n }\r\n<\/pre>\n
The following code is example of function call.<\/p>\n
You will see output value is 2 and 3.<\/strong><\/p>\n
It will ignore 1.<\/strong><\/p>\n
