Markdown is a lightweight markup language designed for creating formatted documents using plain text. It is widely used for its readability and ease of conversion to formats like HTML. Below is a detailed overview of common Markdown elements with practical examples.

Headings

Headings are created by prefixing text with hash symbols (#). The number of hashes indicates the heading level, ranging from 1 (largest) to 6 (smallest).

# Primary Heading
## Secondary Heading
### Tertiary Heading
#### Quaternary Heading
##### Quinary Heading
###### Senary Heading

Paragraphs

Seperate paragraphs with a blank line to ensure proper formatting.

This is the initial paragraph.

This is the subsequent paragraph.

Text Emphasis

Use asterisks (*) or underscores (_) for italic text, double symbols for bold, and triple symbols for bold italic.

*Italicized text*
_Italicized text_

**Bold text**
__Bold text__

***Bold italic text***
___Bold italic text___

Strikethrough

Apply strikethrough using HTML tags or specific Markdown extensions.

<del>This text is struck through</del>

Lists

• Unordered lists utilize asterisks (*), plus signs (+), or hyphens (-).

* First item
* Second item
    * Sub-item 2.1
    * Sub-item 2.2

• Ordered lists employ numbers followed by periods.

1. Initial entry
2. Next entry
    1. Sub-entry 2.1
    2. Sub-entry 2.2

Execute the `print()` function to display output.

• Code blocks are wrapped in triple backticks, optionally specifying a programming language.

function displayMessage() {
    console.log("Greetings!");
}

Tables

Create tables with pipes (|) too separate columns and hyphens (-) for the header row.

| Column A | Column B | Column C |
