Chapter 7 of our JavaScript course dives into the intricacies of object manipulation, object-oriented programming (OOP), and the utilization of built-in objects within JavaScript. We begin by exploring the fundamentals of working with objects, including the use of dot and bracket notations, setting object members, and understanding the concept of "this." The journey progresses into object-oriented programming, where we cover classes, instances, inheritance, encapsulation, and the significance of prototypes in JavaScript. Additionally, the chapter introduces the built-in objects available in JavaScript, highlighting their practical applications. We also explore strings and date-time manipulation, focusing on their properties, methods, and usage in JavaScript programming.
Manipulating Objects in JavaScript
This stage explores how to create and manage JavaScript objects using object literals, dot and bracket notation, and constructors. You'll learn to define properties and methods, access and update object members, and utilize the this keyword for dynamic interactions. Additionally, discover how to use constructors to efficiently generate multiple object instances, enhancing your object-oriented programming skills. Mastering these techniques will enable you to structure data effectively and build scalable, robust web applications.
1 stepsObject-Oriented Programming in JavaScript
Object-oriented programming (OOP) is a programming paradigm that underpins many widely used programming languages, such as Java and C++. This guide provides an in-depth look at the foundational concepts of OOP: classes and instances, inheritance, and encapsulation. Although the examples provided are in pseudocode, the principles discussed apply to many OOP languages.
9 stepsUtilizing Built-In Objects
This stage delves into the concept of global objects in JavaScript, which are built-in objects available in the global scope. Understanding these objects is crucial for effective programming in JavaScript, as they provide essential functionalities and tools. Unlike the global object itself, which represents the global environment, global objects are specific entities accessible throughout the global scope.
15 stepsStrings in JavaScript
This stage covers essential JavaScript string concepts, including string properties like length and various string methods such as concat(), indexOf(), and slice(). Learn how to manipulate and work with strings efficiently using these built-in methods, with practical examples for better understanding.
3 stepsManaging Date and Time in JavaScript
This stage provides a comprehensive guide to JavaScript's Date object, covering its construction, methods, and how to manage date and time. Learn how to work with Date as an integer, handle timezones, and explore the upcoming Temporal API for better date/time manipulation in future JavaScript versions.
