JavaScript – Working with Data Types
JavaScript has 8 Datatypes: String, Number, Bigint, Boolean, Undefined, Null, Symbol, and Object.
JavaScript – Creating an Object
JavaScript objects are variables that can contain many values, and are created using the object literal, the new keyword, or using an object constructor.
JavaScript – Object Properties and Methods
JavaScript object properties can be changed, added, deleted, and mad read only. Object methods are actions that can be performed on objects.
JavaScript – delete Operator
The delete operator deletes a property from an object. It deletes both the value of the property and the property itself.
JavaScript – Object constructor Property
The Object constructor property returns the function that created the Object prototype.
JavaScript – Object.keys() Method
The Object.keys() method returns an array iterator object with the keys of an object, without changing the original object.
JavaScript – Object prototype Property
The Object prototype property allows the addition of new properties and methods to objects.
JavaScript – Object toString() Method
The Object toString() method returns an object as a string or “[object Object]” if it cannot return a string.
JavaScript – Object valueOf() Method
The Object valueOf() method returns the primitive value of an object, or the object itself if it has no primitive.
JavaScript – List of Object Methods and Properties
This is a quick reference list of JavaScript object methods and properties with examples of how they are used.
Python – Working with Classes and Objects
Since Python is an object-oriented, programming language, almost everything is an object with properties and methods.
Python – Inheritance Between Classes
Python inheritance allows a class (child class) to inherit all the methods and properties from another class (parent class).
