What is an object initializer?

Difficulty: 3/10

object literals, property shorthand, spread syntax

1
An object initializer is a comma-delimited list of key value pairs, enclosed in curly braces ({}).
2
More commonly known as Object Literal notation
3
Instead of using a constructor or a class, you literally 'initialize' the object by describing it.

It is the most common and simplest way to create a JavaScript object. In its simplest form, it consists of key: value pairs.

Enhanced Object Literals (ES6+)

1
If the variable name matches the property key, you can omit the value.
2
You can skip the function keyword and the colon when defining methods.
3
You can use square brackets inside the literal to use a dynamic expression or variable as a key.
