Study Notes
JavaScript Overview
- JavaScript is a high-level, dynamic programming language primarily used for enhancing interactivity on websites.
- As of 2022, over 97% of websites utilize JavaScript for client-side webpage behavior.
- It supports multiple programming styles, including imperative, object-oriented, and functional programming.
Primary Uses
- The primary use of JavaScript on websites is to create dynamic content, manage multimedia, animate images, and enable user interaction.
Programming Styles
- JavaScript supports imperative programming, object-oriented programming, and functional programming styles.
- It allows for flexibility in coding practices, accommodating a wide range of developer preferences.
React Framework
- React is a JavaScript library designed for building user interfaces, particularly single-page applications.
- Libraries in React applications provide pre-built components and functionalities that streamline development, promoting code reusability.
Programming Paradigms in React
- React adheres to a component-based architecture, focusing on building encapsulated components that manage their state.
Comments in Programming
- Comments are crucial for providing explanations or annotations in code but do not affect code execution.
- The two main formats for comments in programming are single-line comments (using //) and multi-line comments (using /* ... */).
Misconceptions about Comments
- It's important to recognize that while comments are useful for code readability, they are entirely ignored by the compiler or interpreter and do not influence program performance or output.
Document Object Model (DOM)
- The Document Object Model (DOM) represents the structure of a web document, allowing programming languages to interact with and manipulate elements dynamically.
