JavaScript makes extensive use of objects. What is the term for the various attributes that can be assigned to an object?

• A. Properties
• B. Methods
• C. Keys
• D. Fields

Answer: (A)

In JavaScript, objects are described by properties—name-value pairs that define the data and behavior of the object. Each property has a name (the key) and a value. You access properties with dot notation (object.property) or bracket notation (object['property']). If a property's value is a function, that property is typically called a method, because it provides behavior, but it’s still a property. The term keys refers to the property names themselves, not the values. Fields isn’t standard JavaScript terminology for object attributes. For example, const person = { name: 'Alex', age: 30, greet() { console.log('Hi'); } }; Here name and age are properties with string and number values, while greet is a property whose value is a function, i.e., a method.
