Object literals are a convenient way to create objects in JavaScript. With modern ES6 syntax, object creation is cleaner and more concise, especially when keys and variable names are the same or when using computed property names.

If the key and variable name are the same, you can omit the key name. JavaScript will automatically use the variable name as the key.

You can use a variable or expression inside square brackets [] to define a property name dynamically.

Instead of static keys, you can use variables as dynamic keys in object literals using square brackets.

In ES6, you can define methods without the function keyword. It's shorter and more readable.
