📄️ Variables

Variable Environments

📄️ Modules

Modules are a way to organize and structure code in a more modular and maintainable way. JavaScript modules allow you to split your code into multiple files and then import/export functionality between them.

📄️ Currying

Currying is a technique of transforming a function that takes multiple arguments into a sequence of functions, each taking a single argument and returning another function (until all arguments have been provided).

📄️ Composition

Function Composition is the process of combining multiple functions together so that the output of one function becomes the input of the next.

📄️ Hoisting

It's a mechanism where variables and function declarations are moved to the top of their containing scope during the compile phase, before the code is executed. This means that you can use functions and variables before they are declared in the code.

📄️ Temporal Dead Zone

Variables declared with var are hoisted at the top of their function scope. It means they are initialized with undefined even before the code execution reaches the declaration.

📄️ Scope

A variable declared with var can be access outside it's block scope (not global scope) but not outside of functions local scope.

📄️ Closure

A closure is a feature in JavaScript (and many other programming languages) where an inner function "remembers" the variables and scope of its outer function, even after the outer function has finished executing.
