JavaScript provides different types of values. These are classified as:

JavaScript is a dynamic type language, which means you don't need to specify the type of variable explicitly.

📝 A variable declared with var can hold any data type like numbers, strings, etc.

Example:

var a = 40;        // holding number
var b = "Rahul";   // holding string

These are the most basic data types in JavaScript. They hold single, immutable (unchangeable) values. They are not objects and have no methods.

• Characteristics:
• 🧱 Stored directly in the variable.
• 🧭 Immutable (can't be changed directly).
• 📜 Fast and simple.

These are complex data types. They store references (addresses in memory) to the actual data.

• Characteristics:
• 🧱 Can hold multiple values.
• 🧭 Mutable (you can change their contents).
• 📜 Slower to access compared to primitive types.
