The data type "boolean" in JavaScript is a primitive data type. Primitives are basic data types that represent simple values and are not objects. The boolean primitive has only two possible values: `true` and `false`. It is used to represent logical values in JavaScript, where `true` typically represents a true condition or affirmative state, and `false` represents a false condition or negative state.
Being a primitive means that boolean values are immutable and cannot have properties or methods added to them. When you create a boolean variable, you are directly storing the actual value in the variable, not a reference to an object. This is in contrast to objects, which are more complex and can have properties and methods.
Here's a brief summary:
- Data Type: Primitive (specifically, a boolean)
- Possible Values: `true` or `false`
- Mutability: Immutable (cannot be changed after creation)
- Properties/Methods: Cannot have properties or methods added directly
- Usage: Used for logical operations and conditions in JavaScript.
