The content for the slides was based on consultation with a number of fantastic online resources, including the Eloquent JavaScript and MDN Guide on JavaScript. Those are recommended reading for teachers of this course.
This course gives an overview of using JavaScript to manipulate web pages. It does not cover libraries like jQuery. The course is divided into 3 lessons and is about 5 hours total. The students should be familiar with JavaScript (variables, functions, loops, arrays, objects).
Calculate it! Store your birth year in a variable. Store a future year in a variable. Calculate your 2 possible ages for that year based on the stored values. For example, if you were born in 1988, then in 2026 you'll be either 37 or 38, depending on what month it is in 2026.
Create an array to hold your top choices (colors, presidents, whatever). For each choice, log to the screen a string like: "My #1 choice is blue." Bonus: Change it to log "My 1st choice, "My 2nd choice", "My 3rd choice", picking the right suffix for the number based on what it is. See Solution.
Create 2 functions that calculate properties of a circle, using the definitions here. Create a function called calcCircumfrence: Pass the radius to the function. Calculate the circumference based on the radius, and output "The circumference is NN". Create a function called calcArea: Pass the radius to the function.
JavaScript 101 (Self-paced) A self-paced, beginner-level workshop designed to introduce students to core programming principles and the JavaScript programming language. Class materials and schedule. We will begin day one with brief lectures on basic programming principles and how to use Khan Academy.
Variables are one of the basic building blocks of Javascript. Just like 'x' in algebra, a variable in programming is a named container for a value that can change. Variables have to be 'declared' once before being used, using the 'var' keyword and the name of the variable.
Javascript has a more complex data type called an 'object'. Objects allow us to describe an entity that has a complex structure, and more closely resembles something that exist in the real world. Arrays and functions are both special types of objects in Javascript.
Review: Terminology. In the following code, name the data types used, describe the scope for the variables, and spot the: statement, variable, expression, operator, function, argument, and return value. function calculateTip(total) {. var tipPercent = 0.15;
Keep track of which books you read and which books you want to read! Create an array of objects, where each object describes a book and has properties for the title (a string), author (a string), and alreadyRead (a boolean indicating if you read it yet). Iterate through the array of books.
