Key JavaScript Concepts & Tools
Variables
Store data using `let`, `const`, or `var` to manage values like numbers, strings, or objects.
Functions
Reusable blocks of code that perform tasks, defined with `function` or arrow syntax.
Arrays
Store lists of data and manipulate them with methods like `map`, `filter`, and `forEach`.
Objects
Key-value pairs for structured data, used to model real-world entities.
Loops
Repeat tasks with `for`, `while`, or `for...of` to iterate over data efficiently.
Conditionals
Control flow with `if`, `else`, and `switch` to make decisions in your code.
DOM Manipulation
Interact with web pages using the Document Object Model to create dynamic content.
Events
Respond to user actions like clicks or keypresses with event listeners.
Promises
Handle asynchronous operations like API calls with `Promise` and `async/await`.
Fetch API
Make HTTP requests to retrieve data from APIs for dynamic web apps.
ES6 Modules
Organize code with `import` and `export` for modular, reusable scripts.
Node.js
Run JavaScript on the server to build backend applications and APIs.
React
Build interactive user interfaces with this popular JavaScript library.
VS Code
A powerful code editor with JavaScript support, extensions, and debugging tools.
Chrome DevTools
Debug and optimize JavaScript with browser tools for inspecting and profiling.
Git
Version control system to track and collaborate on JavaScript projects.
