Mobile Development and JavaScript

Overview

This course is the first in a series that will allow you to expand your skills as an Android developer into the world of cross-platform mobile development. This will allow you to use your foundations as an Android developer to build cross-platform mobile applications. The first step in this expansion is learning to program in JavaScript. This will prepare you to learn to use the React library for mobile development. JavaScript is the programming language that powers the modern web. In this course, you will learn the basic concepts of web development with JavaScript. You will work with functions, objects, arrays, variables, data types, the HTML DOM, and much more. You will learn how to use JavaScript and discover interactive possibilities with modern JavaScript technologies. Finally, you will learn about the practice of testing code and how to write a unit test using Jest. This course can be applied to multiple Specializations or Professional Certificates programs. Completing this course will count towards your learning in any of the following programs: • Meta Android Developer Professional Certificate • Meta iOS Developer Professional Certificate By the end of this course you will be able to: • Explain the basic concepts of web development with Javavscript. • Practice using functions, objects, arrays, variables, data types, the HTML DOM, and much more. • Use JavaScript within the React framework • Practice testing code and how to write a unit test using Jest

Syllabus

Introduction to Javascript

In this module, you are introduced to JavaScript. You'll learn why JavaScript is so integral to software development. And you'll get an overview of how to write JavaScript code inside the browser. Furthermore, you will learn about the most common operators as well as conditional statements and loops.

The building blocks of a program

Here you'll learn how to use objects, arrays and functions. In addition, you will learn about the most common built-in methods, and the difference between undefined, null and empty strings. And you'll explore both error handling and defensive programming.

Programming paradigms

This module is about functional programming and the object oriented programming paradigm. You will learn what scope is in JavaScript. You'll explore the differences between var, let and const. And you'll learn how to use classes and inheritance in object oriented programming. Additionally, you'll explore how to use write JavaScript using modern features like spread and rest. You will build code that can manipulate the DOM and handle events. And you will use JSON in JavaScript.

Testing and compatibility

Here you will learn about Node.js and npm. And you will explore how to install npm packages and how to work with package.json. Furthermore, you will learn about testing in JavaScript and you'll code a simple unit test in Jest.

Final Project

In the final module, you'll learn about the graded assessment. After you complete the individual units in this module, you'll synthesize the skills you gained from the course to create code for the "Little lemon receipt maker". You'll also have to opportunity to reflect on the course content and the learning path that lies ahead.
