Closures are a powerful feature in JavaScript that allow functions to retain access to their lexical scope even when executed outside their original context. This concept is essential for creating private variables, implementing partial applications, and more.

Hoisting is an essential JavaScript concept that affects how variables are handled by the interpreter. This post explains how hoisting works with `var`, `let`, and `const`, and how to avoid common pitfalls.

JavaScript is a single-threaded language, meaning it can only execute one task at a time. However, it can handle both synchronous and asynchronous operations with the help of tools like the Call Stack, Event Loop, and Task Queues. Understanding these concepts is crucial for efficient coding.

What is the Call Stack in JavaScript?

Event Loop and Task Queues Explained

When a function is called, it is pushed onto the Call Stack.

If the function calls another function, the new function is pushed onto the stack.

When the Call Stack is empty, the Event Loop checks the Task Queue to push any pending tasks.
