Congratulations for seeing one of the best tweets you will read online today; we are starting our JavaScript coding Journey from scratch on a full:

Course Title: HTML, CSS & JAVASCRIPT
Topic: Introduction to JavaScript

I’ll explain in detail, kindly retweet for others, and open

I want to specifically congratulate you for coming this far. Thousands of people started with us, and thousands have dropped halfway despite HTML and CSS being the simplest of what's to come.

Understandably so, I do not blame them, never, because tech/coding is not for everyone.

Welcome to your first javascript class. Kindly ensure you are following me and put on my Tweet notification to avoid missing subsequent classes, dev tips, tech spaces & mentorship.

If you're new, you can still catch up with us, follow me & start your journey from my pinned tweet

INTRODUCTION TO JAVASCRIPT
So far, we’ve used HTML to arrange our web pages’ content and CSS to style it.

For exp, one of the primary reasons we use Javascript to create interactivity is that it allows us to control the Document-Object Model (often known as the DOM for short).

By leveraging on Javascript, we can alter the Document Object Model (DOM) to perform operations such as:

Make changes to existing HTML components.
Make changes to the attributes of HTML elements.
HTML elements can have their CSS stylesheets modified or added.
HTML elements can

be added and removed.

NOTE
*You must read full class from akinolaakeem.com/introduction-t…

*JavaScript is also known as "js", not Java
*I will be using the JavaScript comment sign // to explain in my code
* Only those with VsCode can check their code output by using the Console tab.

1. Javascript Data Types

Declaring a variable is accomplished through the usage of the var statement. A variable is handy for storing information that we may wish to use later.

The console.log() prints to the console whatever data is supplied to it between the parenthesis. exp

Think for a moment: what do you aim this code to accomplish?

Javascript examines the declared variables and decides that they are both numbers. Javascript then understands that it must print the total of the two values to the console.

The output for the code below will be 30.

2. JavaScript: Numbers
Javascript uses 64 bits of memory to encode all numbers.

Each bit corresponds to a binary value (e.g., 0 or 1). The maximum integer you can express with 64 bits is 2^63 – 1, or 9223372036854775807.

3. Adding & subtracting numbers
Use the + operator to add numbers and the - operator to subtract numbers.

Again, always check the word after //; I am using them to explain the code in the example for you.

4. Multiplying & dividing numbers

Looking at the code below, you have said the following

Variables of 10 should be multiplied by 10; hence the first 10*10
Variables of 10 Should be divided by 5; hence the second 10/5
Variables of 10 Should be divided by 3; hence the third 10/3

5. The Modulo Operator

6. Order of operations

Operations take place from left to right in order of precedence, meaning certain operators are prioritized more than others. In general:

Your output after requesting console.log for number1, number2, number3 = 100, 190, 0 respectively

7. Incrementing/Decrementing Number Values

You can increase or decrease a number’s value by adding, subtracting, multiplying, or dividing it by another number:

Your output will be

Add 10=20
Subtract 5=15
Multiply by 7=105
Divide by 5=21

8. ++ and -- Operators
There are many instances where you will want to increment or decrement a value by one.

In this case, you can use the ++ and -- operators as a further shorthand:

That is the end of our JavaScript class for today. JavaScript may be hard but not for us.
