Objects are entities used to represent real-world objects in OOP. Classes are used to create objects in programming. Let’s use an automobile as an example to understand better. The components that make up the car are referred to as objects, and the vehicle is referred to as a class. A built-in function in TypeScript facilitates the use of classes in programs. This is due to its support from ES6 and later versions. Classes were not supported in older versions of JavaScript.
