In the below example, we will see we can access private variable in the same class. publicclassMain{/* Declare private variable named x */privateintx;/* Define constructor for privatevariable initialization */Main(intx){this.x=x;}/* Define method to print value of variable x */publicvoi...
the _count variable can not be touched outside the class constructor, effectively making it private. This is cool, sure. But how do we operate on the value of _count? We can do the same thing as this.getCount() because everything in the constructor has block-level access to _count,...
As noted above in the code comments, the act of settinggk.raceto some value did NOT overwrite the privateracevariable. Although it would be a dumb idea, you can have both private and public variables with the same name. For example, theyell()method in the following class will yield diffe...

Introduction and code samples on using private class fields in JavaScript.Before the introduction of private class fields, we could not really enforce private properties on a class. We used conventions instead, maybe using _ as an hint that the field is private, like this:...
You can use number as function/variable name, the numberic name can't be accessed from parent scope, but can be accessed by 'this' in private scope. varo={ attr1:'value of attr1',1:'private attr ,the index is 1',301:function(){ ...
In JavaScript, developers often hide a lot more than just “methods”. Modules, classes, and even entire programs can all be private. In fact, it’s not uncommon to see a library that doesn’t expose a single global variable. Due to the nature of the browser environment, code is kept ...
