JavaScript Masterclass - Zero to Job-Ready with Hands-On Projects - Object Literals - I

The video introduces object literals as a data type that allows storing multiple items with properties and methods, contrasting them with arrays, which are limited to storing similar types of data indexed by position. Object literals provide flexibility to store diverse information and functionalities, making them suitable for complex data structures. The lecture concludes with a promise to delve deeper into syntax and practical applications in the next session.

What is the primary use of arrays as discussed in the video?

• To store multiple types of data about a single entity

• To store similar types of data together

• To store data with unique keys

• To store data in a hierarchical structure

What is a major limitation of arrays mentioned in the video?

• They can only store numbers

• They rely on index positions and store similar types of data

• They cannot store any data

• They are not indexed

Why might object literals be preferred over arrays in certain cases?

• They are faster to access

• They are easier to sort

• They can store multiple properties and methods for a single entity

• They use less memory

Which of the following is a feature of object literals?

• They can only store strings

• They can store properties and methods

• They are limited to storing numbers

• They cannot be modified once created

What can object literals store that arrays cannot?

• Only numbers

• Only strings

• Multiple properties and methods for a single entity

• Only boolean values
