Which of the following is the correct way to define an object in JavaScript?
a) var obj = { key: value };
b) var obj = [ key, value ];
c) var obj = “key = value”;
d) var obj = (key, value);
Answer:
a) var obj = { key: value };
Explanation:
In JavaScript, objects are defined using curly braces {} and consist of key-value pairs. The keys represent properties, and the values can be any valid data type.
Example:
var person = {
name: "John",
age: 30,
isStudent: false
};
console.log(person.name); // Output: "John"
