JAVASCRIPT
Java script full course beginner to pro
The complete JavaScript course, which aims to teach beginners the basics of JavaScript
and take them all the way to a professional level. The topics covered include creating
interactive websites using JavaScript together with HTML and CSS, with a final project of
building Amazon.com. Part one of the course covers the fundamental features of JavaScript,
while part two teaches skills needed for bigger and more complex projects. The course
offers over 200 exercises and is suitable for learners with no prior coding experience. The
instructor also provides solutions to any issues the learners may face throughout the course.
JavaScript works by showing viewers how to give instructions to a computer and make it
follow the instructions. The video demonstrates using Google Chrome to access the console,
where users can enter code to instruct the computer. The console is used to create pop-up
messages, perform math calculations, and understand basic programming terminology. The
instructor highlights the importance of typing the code exactly as shown since even small
typos can result in errors. The video concludes by emphasising how programming
languages like JavaScript allow developers to communicate with computers and automate
tasks.
The basics of JavaScript and demonstrates how to modify a webpage by replacing its
content with a simple text using JavaScript code. The instructor explains that JavaScript is
all about giving instructions to the computer and following the rules of the language's syntax,
similar to following grammar rules in English. They also emphasize the importance of
understanding syntax and the consequences of not following the rules precisely, as this
could result in syntax errors that prevent the computer from understanding our code. The
instructor concludes by providing some exercises to practice what was learned in the lesson
and promising to delve deeper into the various features of JavaScript in subsequent
sections.
The JavaScript Full Course, the instructor introduces the concept of numbers and math in
JavaScript through a project that involves creating an e-commerce website similar to
Amazon. The focus is on the section that calculates the cost of the cart, including the cost of
products, shipping, and taxes. The syntax rules for math in JavaScript are explained, with
examples of addition, subtraction, multiplication, division, and handling of decimal numbers.
Practical examples are also provided, such as calculating the cost of products before
shipping and taxe
The JavaScript Full Course, the instructor demonstrates how to use JavaScript to calculate
numbers by multiplying and adding them. The video goes over the concept of the order of
operations, which includes adding, subtracting, multiplying, and dividing. The video also
covers bracket syntax rules and how to use parentheses in JavaScript to control which part
of the calculation gets done first. Overall, this section provides a beginner level introduction
to basic arithmetic and syntax in JavaScript.
The instructor continues with the basics of JavaScript and introduces the concept of order of
operations in calculations. He uses practical examples to teach how to use brackets to group
calculations and how to calculate percentages manually. The students practice calculating
the cost of products and taxes using order of operations and learn how to avoid incorrect
calculations. The instructor also explains how to make the resulting numbers more accurate
by rounding them down.
, How to use brackets to control how JavaScript computes numbers and math, which is
necessary when calculating money, for example. The video also discusses how computers
store floating point numbers inaccurately due to limitations, but notes that computers can
store whole numbers, called integers, without a problem.
How to avoid inaccuracies when working with money in programming by calculating in cents
instead of dollars. They demonstrate this process by converting a dollar amount to cents and
back again, and then introduce the concept of rounding numbers in JavaScript using the
command "Math.round(x)" where x is the number to be rounded. They then show how to use
this command to round a calculated tax amount to a specific decimal point.
How to work with numbers, perform calculations, and how to handle rounding of numbers in
JavaScript. They also explain how to search for existing JavaScript code using Google to
learn new features of the language. The instructor stresses that the examples provided in
this section are simple, and that while math is important, it's not necessary to have advanced
math skills to learn JavaScript. Lastly, the instructor provides links to AI tools that can help
search for code.
The concept of strings in JavaScript, which represent text. The instructor provides syntax
rules for creating strings and illustrates how to combine two or more strings using
concatenation. The video also demonstrates how to check the type of value using the
'typeof' command and how JavaScript converts numbers to strings when added to a string."
In this section, the video tutorial covers practical examples of using strings and numbers in
JavaScript to create text. The instructor demonstrates how to add the costs of a basketball
and a t-shirt together to create the total cost with a dollar sign included in the string.
However, using the plus operator with strings and numbers can lead to automatic type
conversion and inaccurate calculations with floats. Therefore, the instructor recommends
using brackets to control the order of operations and calculate in cents to avoid inaccuracies
when dealing with money.
How to use strings and numbers in JavaScript to create text and perform calculations. We
start by creating a simple string that displays the cost of an item and then move on to a more
complicated example that involves calculating a quantity and adding it to a string. We also
learn how to use brackets to control the order of operations when combining strings and
numbers. Finally, we create a popup that displays the resulting string and learn about the
different ways to create strinbeginneJavaScript
ection of the course, we learn about creating strings in JavaScript. There are two ways to
create strings, using single quotes or double quotes, but single quotes are recommended
because they are easier to read and type. However, if there is a single quote inside the
string, we can use double quotes or an escape character, which is a backslash followed by
another character like a single or double quote, to create the string. There are also escape
characters for creating new lines of text.
we learn about the various ways of creating a string in JavaScript, including using escape
characters, single and double quotes, and back ticks. Back ticks are used to create template
strings, which have two special features: interpolation and multi-line strings. With
interpolation, we can insert values directly into a string using dollar open curly bracket and
close curly bracket. Multi-line strings are strings that span across multiple lines and are only
available for template strings. We'll learn to use multi-line strings later in the course.
We learned about strings and the different ways of creating them. Single quotes are
recommended by default, and template strings should be used when inserting values into
the string or typing the string on multiple lines. The next section of the course will cover how
to use HTML, CSS, and JavaScript together to build a website. To do so, we will need a
