Lecture Notes: JavaScript DOM Manipulation

Key Points

Cloning an element and appending it multiple times in HTML is more efficient than writing HTML manually.
Condition for appending: the element to be appended should not be a parent element.
Without cloning, appending an element cuts and pastes it like a cut-paste operation.
Cloning copies the original element.

Introduced new topic: creating new elements using JavaScript and appending them to HTML.
Setup includes an HTML layout with Pokémon images for demonstration.

Pokémon characters used as examples for creating and appending elements.
Provided an overview of accessing Pokémon images via an external repository or API.
Dynamic number substitution in URLs to fetch different Pokémon images.

Cloning Existing Elements: Selection and cloning of images without current availability in HTML (using JavaScript memory references).
Creating Elements from Scratch: Steps to create new elements and set attributes like 'src' for images.
Using Document.createElement: Demonstrated with practical examples creating new elements like <p> (paragraph) and <img> (image).
Appending New Elements: How to append newly created elements to the DOM.

Example of setting IDs and classes to newly created elements.
Importance of setting properties before appending to avoid showing empty elements initially.

Brief explanation of inline vs block elements using custom element examples like <anurag>.

Usage of different variables and string templates to dynamically create elements and append multiple times in a loop.
Efficient methods to set inner HTML content.

Create a dynamic list of 100 Pokémon images using JavaScript.
Include the number below each image for identification.
Demonstration should follow the template provided in the lecture for consistent practice.
