JavaScript Full Course (2023) - Beginner to
Pro
Part 1
Learn JavaScript from Beginner to
Professional:
In this course, we're going to learn how to build complex websites using
JavaScript from a beginner to a professional level. This course will cover
everything that you need to learn JavaScript. You don't need any previous
coding or technical experience to follow along.
Below the video, you can find the different lessons of this course:
Lesson 1: Introduction to JavaScript
Lesson 2: Variables and Data Types
Lesson 3: Functions and Parameters
Lesson 4: Loops and Conditionals
Lesson 5: Objects and Arrays
After each lesson, I'm going to give you a bunch of exercises that you can
do on your own to practice the skills.
This course is focused on JavaScript. If you want to learn HTML and CSS in
more detail, I have a full course just like this one that you can find in the
video description.
The easiest way to understand JavaScript is that we're basically giving
instructions to a computer and then the computer follows our
instructions. We're giving instructions to a computer and then the
computer follows our instructions. This is called running the code. There
are many different languages we can use to write code called
programming languages. Some examples of programming languages are
, JavaScript, Python, and Java. So here we're writing our code using the
JavaScript programming language.
In this example, we will be using JavaScript to modify a webpage.
Modifying webpages is one of the most important features of JavaScript.
By giving instructions to a computer, it will follow our instructions or "run
the code". Don't worry about memorising all this code - in this lesson we
will learn that JavaScript is basically about giving instructions to a
computer. We will write our first few lines of JavaScript code and learn
how to run them using the console in our web browser. We will also learn
about syntax, which are the rules that we need to follow when writing
our code. Here are some exercises you can try on your own to test what
we've learned:
JavaScript can handle math with more than two numbers. For example, if
we add 1, 2 and 3 and press enter, the computer will add these three
numbers together and result in six.
JavaScript can also handle decimal numbers, such as 2.2 + 2.
If needed, you can modify your shopping cart on this webpage by clicking
"Update" or "Delete", or adding any products that you're missing.
The way math normally works is that multiply and divide are done first.
Add and subtract are done after this is called the order of operations.
This is also called operator precedence in JavaScript. JavaScript follows
the same rules. Another feature is that we can use brackets to control
which part of the calculation gets done first and then do the rest.
We're going to learn how to calculate this 10% tax here. We'll type 36.93
multiplied by 10% or 0.1. If we press enter, it will give us a number that
is close to what we have in the final project. However, this number is
more accurate than we need. Later in this lesson, we'll learn how we'll be
able to round this number down to exactly what we've got.
The first detail we're going to learn is a weird behavior of math in
JavaScript. The reason this happens is because of how computers store
numbers. Computers can only store zeros and ones while humans can
