JavaScript is a dynamically typed language, meaning the type of a variable is determined by the value assigned to it rather than being explicitly declared.

Functions help organize code, reduce repetition, and improve readability.

An object is a data structure used to store multiple values in a single variable using key–value pairs.

JavaScript provides two advanced data structures: Map (stores key-value pairs) , Set (stores unique values)

Modern JavaScript provides powerful syntax features to work with arrays, objects, and function parameters efficiently.

It allows programs to make decisions and execute different code paths depending on the result of logical expressions.

Looping allows a program to execute a block of code repeatedly until a specified condition is met.

Modularization is a software development technique that divides a program into smaller, independent, and reusable modules.

Asynchronous programming allows JavaScript to execute tasks without blocking the main thread.
