In JavaScript, var, let, and const are used for variable declarations, but they differ in their scope, hoisting behavior, and mutability.
**var**: Declares variables with function scope, is hoisted, and can be redeclared and reassigned.
**let**: Introduces block scope, is not hoisted, and can be reassigned but not redeclared.
**const**: Also introduces block scope, is not hoisted, and cannot be reassigned or redeclared.

Understanding these differences is crucial for writing maintainable and bug-free JavaScript code.
