What is the difference between an object literal and a class in JavaScript?
An object literal is a simple way to create an object using key-value pairs, while a class is a blueprint for creating objects with shared properties and methods.
Can you give me an example of each?
Sure! An object literal looks like this: const obj = { name: 'Alice', age: 25 };
A class example would be: class Person { constructor(name, age) { this.name = name; this.age = age; } }
.
When should I use an object literal instead of a class?
Use an object literal for simple, one-off objects. Use a class when you need multiple instances with shared behavior.
Are there any performance differences between the two?
Generally, object literals are faster for creating single objects, while classes are more efficient for creating multiple instances.
