JavaScript Basics

Explain the history of JavaScript, run JavaScript code in the browser console and use console.log statements in JavaScript to log out values.

Declare variables in JavaScript to represent data. Define and use number, string, and Boolean data types. Use operators to manipulate numbers. Use string properties and methods to manipulate strings. Use strong and loose equality in comparisons.

Add conditional logic to control program flow. Identify truthy and falsy values. Deploy ternary operators for more concise conditional logic and use switch statements to chain multiple else if conditions.

Use for and while loops to reduce code duplication and automate repetitive tasks. Nest loops for more complex automation and use assignment operators to write more concise code.

Create and run JavaScript functions to streamline and organize code. Use return statements to return items when a function runs. Explain how scope works in JavaScript. Use let and const in block scope. Store functions in variables using function expressions and use inline function expressions.

Create and use JavaScript arrays to store a collection of data. Use indexes to reference an array element. Deploy array properties and methods including length, push, pop, and splice to manipulate arrays. Loop through arrays using forEach and map.

Create and use JavaScript objects to store a collection of data as key:value pairs. Use dot notation and bracket notation to access object elements. Add and access methods in JavaScript objects.

In this project, you'll use your JavaScript development skills to build the core functionality of an eCommerce shopping cart for Kirana’s fruit market. You will create a collection of products and then write the JavaScript code to add, remove, and change the quantity of a product in a shopping cart. You'll also write the JavaScript code for the checkout functions: making a purchase and returning change.
