- Intro to Programming with Javascript4:51
Learn the basics of programming with JavaScript, covering object oriented and functional concepts, and apply them to web pages using the DOM, CSS, and browser debugging in Chrome.
- The Look of Javascript10:19
Explore the look and feel of JavaScript by examining its text-based syntax, variables, properties, and methods. Learn to use the browser console for basic debugging and experimentation.
- Variables4:43
Define variables in Javascript, perform basic algebra with +, -, asterisk for multiplication, forward slash for division, and use parentheses to enforce the order of operation.
- Inside HTML9:03
Embed JavaScript in a web page with script tags, place the script after the body for loaded elements, define variables like a and b, and log expressions with console.log.
- Objects9:11
Discover how JavaScript treats almost everything as an object and use dot notation to access window, document, and location. Inspect objects with the console to view URL components.
- Alert5:33
Learn how to use the window alert to display strings, numbers, or variables, and avoid single vs double quotes and syntax errors.
- Comments3:18
Learn how to replace alerts with document.write and master JavaScript comments, including single-line // and multi-line /* */, to annotate code and temporarily disable sections while you code.
- document.write5:57
Write text to the document using strings in quotation marks, and use document.write with the plus operator to concatenate strings and print variables alongside text.
- getElementByld8:15
Learn to access a page element by its id using document.getElementById, assign it to a variable, and update its innerHTML to reflect changes.
- Events6:59
Learn how to trigger JavaScript with page events like on load and on click, and manipulate the document using get element by id to respond to user actions.
- Value Types7:48
Explore basic JavaScript data types: numbers, strings, booleans, and arrays, including creating arrays, storing values like colors and Fibonacci numbers, and accessing elements by zero-based indices.
- JSON8:07
Explore creating arrays with shorthand notation and array literals, and build a car object with named indices like make, model, and year, then access values via dot or bracket notation.
- Operators6:18
Master JavaScript operators, including math operators and assignment operators such as equals and plus equals, and learn increment and decrement with pre and post forms.
- Course Check List1:01
Review the course check list for the JavaScript course to ensure you complete the essential steps and stay aligned with the program requirements.
- Numbers8:08
Learn how numbers and strings differ in JavaScript, and use number methods like toFixed and toPrecision to format numbers for display while preserving math precision.
- Strings12:48
Learn JavaScript strings by creating hello and world, then joining them, and explore length, search, substring, index, and text methods such as toUpperCase, split, and replace.
- Functions9:51
Learn how functions and methods differ in JavaScript, create reusable custom functions with parameters, and apply them to change the page background color.
- Variable Scope4:53
Explore how global and local scope define where variables exist, how window scope relates to function scope, and how locals override globals.
- Return Values5:26
Emphasize functions as value types by assigning them to a variable and using return to produce a calculated value, such as two numbers divided by each other.
- Typeof7:14
Explore JavaScript value types—numbers, strings, booleans, arrays, and objects—and use typeof to identify types and convert strings to numbers with a plus in front of it.
- Course Check List1:01
Use a JavaScript course checklist to guide your learning and navigate the curriculum, ensuring you complete essential activities.
- Intro0:47
Explore the Math object and the Date object to perform math and create dates for today or past and future times, then learn statements and loops to control flow.
- Math7:56
Explore the JavaScript math object, using constants like pi and sqrt, and methods for max, min, rounding (round, floor, ceil), and random numbers to perform geometry and basic math tasks.
- Random7:40
Generate random numbers in JavaScript with Math.random, and use round, floor, or ceil to produce 0-1, 0-4, or 1-5 ranges, via a function.
- Range Function6:01
Create a range function that takes min and max, computes their distance, generates a random value with Math.random, adds the min, and returns ceiling value; shown with 5-10 and 100-200.
- Date14:24
Explore the JavaScript Date object, create and format dates with new Date(), extract and set year, month, date, and time, and implement leading-zero formatting for clean, calendar-ready strings.
- If Else10:30
Explore how to use if else and else if in JavaScript, with functions and the arguments object to handle defaults and leading zeros.
- Loops: While8:05
Explore how while loops use a condition to repeat code, and how arrays are traversed with pop and console.log until no elements remain.
- Loops: Do While4:38
Demonstrates how the do while loop executes code at least once before evaluating the condition, using a colors array and colors.length to log no colors available.
- Loops: For11:42
Learn how to replace a while loop with a for loop to iterate over arrays, using an iterator, length checks, and start-end indices, with logging colors and image sequences.
- Loops: For In9:57
Learn the JavaScript for in loop, iterating over an object's named properties with a current key and bracket syntax. Use break and continue to control flow.
- Course Check List1:01
Follow the javascript course checklist to organize the course content and track your progress through the course.
- Section 41:04
Learn how JavaScript handles user interaction by working with forms, images, and timers to create image rollovers and a slideshow that changes over time.
- OnFocuse OnBlur13:51
Learn how to use JavaScript focus and blur events to style form elements, access them by id, and create reusable functions to change borders and colors.
- OhChange18:28
Explore how onchange updates dropdowns and checkboxes in real time, changes background color and night mode, and uses focus, blur, and HTML5 inputs for validation.
- Images: Preload, Mouseover14:12
Master image rollovers by using thumbnails to update a large image on mouseover, preload images into an array, and simplify with a for loop for instant switching.
- Timers12:44
Master the use of timers in JavaScript with setTimeout and setInterval to trigger single or repeating actions, such as changing the background color from a color array.
