Exploring the mysteries of "point" grammar

Dot syntax

All along, you don't understand what a point syntax is, it's the equivalent of a link or a path. Maybe I browsed less information, read a few related blog posts, there is no record, this is only a preliminary analysis of insights.

In JavaScript, properties and methods are accessed using the "dot" syntax:

Object.property accesses data in an object by means of a     property Object.Method ()      accesses the data in the object through the form of a method

So, ". Dot is the operator of the Access object property, method in JS.

According to this period of time after learning JSON observation found: Point syntax operation, first "." Have to be an object.

JSON first converted to JSON object

Oh! Yes, there are arrays, which are converted to array objects.

var Lennon = Array ();  or var Lennon = Object ();   < recommended Use >lennon.name = "Xiaoyaochaoer"; lennon.age = 23;

PS: All variables in JavaScript are actually objects of some kind.
