Course Description
JavaScript 101: JavaScript for absolute beginners
If you have never written any JavaScript, this course is absolutely for you.
We're going to get started at the very beginning, even if you don't have a code editing program installed on your computer.
The short version:
Look, here's the short version:
If you are interested in learning JavaScript from scratch, this is the course for you. Try it out on Udemy, there's nothing to lose if you don't like it.
Beginner friendly:
This course is designed for beginners. You should already know some HTML and a little CSS at this point and that will make learning JavaScript a lot easier.
JavaScript is nothing like HTML or CSS though because JavaScript is a REAL programming language, whereas HTML and CSS are not programming languages.
Modern JavaScript included:
Just because this is a beginner-friendly course doesn't mean you shouldn't learn the ins-and-outs of modern JavaScript. You will learn about modern JavaScript concepts such as:
let/const variables
template literals
fat arrow functions
forEach function-based loops
object literals
node selectors and query selectors
and much more
Practice:
There is A LOT of practice (hands on coding) in this course. And you'll be writing code from the very first lesson!
Plus there's a very interactive project at the end of this course.
In this course you will learn these major concepts:
JavaScript syntax
Where to put your JavaScript and how it affects your page
How to debug your JavaScript using developer tools (Inspect tools, console logging, and more)
Storing variables with var, let, and const JavaScript variable types (Variables)
How to tell a computer what to do based on certain circumstances (Conditionals)
The Document Object Model (DOM)
Making custom sentences with string concatenation and template literals
Data types and structures and why they're important (Data structures)
How to make lists and take an action on every item in that list (Iteration)
How to select elements on your web page and change them
Functions, function parameters, and how to use JavaScript rests
Final Project:
Lastly, there's a final project that will make use of almost everything you will have learned in this course.
Requirements:
To start learning JavaScript you should know a little HTML and CSS. These aren't hard requirements, but I strongly suggest knowing the basics of HTML and CSS before learning JavaScript.
JavaScript is how you make your page interactive, so you'll need to know how to make a basic webpage first.
Basic HTML
Basic CSS
Who is JavaScript 101 for?
If you've never written any JavaScript in your life, this course is for you.
If you just finished learning HTML and CSS, this course is for you.
If you want to learn modern JavaScript in an easy way, this course is for you.
If you want lots of hands on practice writing JavaScript, this course is for you.
––
If you already know JavaScript, this course is NOT for you.
If you know about features such as fat arrow functions and object literals, this course is NOT for you.
If you already know how to manipulate the DOM using JavaScript, this course is NOT for you.

It is not yet clear to me after learning this course, how am I going to use Java script while developing a website. You must show how and where Java Script is used while developing a website.

I've been able to grasp everything so far. I love the way you go about teaching. I have taken your html and css course and learned a lot from them. You're a great teacher Kalob.

I was always wondering about usage of console while I was learning HTML and CSS. My questions are totally answered. It is time to move Kalob's other 2 JavaScript Lessons.

i love how detailed oriented the teacher is and one is able to learn with ease
By Snazzy Sensei on 11/17/2020
Knowledgeable instructor, great teaching methods, clear and concise explanations sorta sums up this course. Oh and he keeps on pushing you with "homework" and quizzes. The best part is the last project which is to find and fix a problem on a js file on a website. It kinda feels more real than just fixing a random practice file if you know what I mean.
By Ryan Avejar on 11/16/2020
Definitely another 5* course from Mr. Kalob. He is one of the best instructors online that you can find. I'm also a member of his growing community on facebook and I am sure you'll gonna enjoy his courses including this brand new one!. Thank you Mr. Kalob for this superb JS101 course.
