Arrays are objects that store other objects. You can think of an array as a bag that you can throw items in. The bag itself is an object, along with the other items you store inside the bag. Ruby arrays are a very popular data structure, and they can be used to store many different data types. Today, we’re going to take a look at some of the common Ruby array methods every dev should know.

We’ll cover:

• What are array methods in Ruby?
• Common array methods
• Advanced array concepts and next steps

Enumerations (or enums) are a supported data type in TypeScript. Enums are used in most object-oriented programming languages like Java and C# and are now available in TypeScript too. They are one of the few features of TypeScript which isn’t a type-level extension of JavaScript. Enums allow you to define a set of named constants. Using them makes it easier to document intent or create a set of distinct cases. Today, we’ll explore the basics of TypeScript enums along with use cases, various enum types, and next steps for your learning.

We’ll cover:

• What is enum in TypeScript?
