Variables are memory locations that store values.
Values are entities manipulated, changed, or used to create other values.
- Example: "Honda" can be the value of the car variable.
Data types represent specific categories of values.
- Example: Number, string, boolean, and others.
Other Data types represent specific categories of complex values.
- Example: Array ( [] ) or Object ( {} ).
Operators are symbols that facilitate mathematical operations.
- Example: *, -, !, +.
Operators are symbols that facilitate logical operations.
- Example: !, &&, ||.
Comparison operators are used in logical statements to determine equality or difference between variables or values.
- Example: ===, !==, >, <
Conditional control flow in JavaScript involves making decisions in your code based on certain conditions. It allows your program to execute different blocks of code depending on whether a given condition is true or false.
Loops involve repeating tasks in the same sequence under specific conditions.
- Example: For-loop, while-loop, do-while-loop.
Functions are blocks of code designed for repetitive execution.
- Declaration
- Invocation
- Parameters and Arguments
- Return Statement
- Expression
- Arrow Function
- Anonymous
- Hoisting
- Callback
- Methods
- Recursion
- Rest and Spread
Async deals with concurrency in asynchronous programming.
- Understand asynchronous programming, callbacks, promises, and async/await syntax.
- Learn how to handle asynchronous tasks, such as fetching data from APIs.
ES6+ introduces arrow functions, template literals, destructuring, and classes.
OOP signifies that everything is an object.
- Learn basics, including object creation, inheritance, and encapsulation.

Web APIs provide a standardized way for different software systems to communicate over the web.
A library is a collection of pre-written code that can be used in your program.
- Example: Moment, Axios, etc.
Frameworks are comprehensive sets of tools and rules designed to structure and guide the development of a particular type of software.
- Example: Nestjs, Express, Fastify.
Learn server-side development with Node.js.
- Understand how to use npm (Node Package Manager) to manage dependencies.
Version control systems such as Git and GitHub enable efficient collaboration and code management.
A database is a structured collection of data organized for efficient storage, retrieval, and management.
- Relational

Debugging is the art of finding and fixing problems in the code.
Formatting involves beautifying the code for improved readability.
Testing is crucial and should be conducted at various levels to ensure code reliability.
The programming environment specifies the context of development, such as dev, staging, and prod.
