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 – Displaying Object Properties
JavaScript object properties can be displayed according to name, within a loop, using Object.values(), or using JSON.stringify().
JavaScript – Using Object Constructors
When many JavaScript objects of the same type need to be created, an “object type” can be be created using an object constructor function.
JavaScript – The “this” Keyword in Objects
In JavaScript, the this keyword is used to refer to various objects.
JavaScript – Destructuring Objects
In JavaScript Objects, unpacking the object properties into variables is called destructuring.
JavaScript – Object Iterations
In JavaScript, there are numerous ways to iterate though the properties of an object.
JavaScript – Object Management
In JavaScript, there are numerous methods used to manage an object by accessing, changing, or returning properties.
JavaScript – Object Accessors
In JavaScript, getters and setters allow you to define Object Accessors (Computed Properties).
JavaScript – Object Protection
In JavaScript, there are numerous ways to protect an Object from being changed.
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.assign() Method
The JavaScript Object.assign() method copies properties from one or more source objects to a target object.
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.
