February 17, 2026 - As we know from the chapter Data types, there are eight data types in JavaScript. Seven of them are called “primitive”, because their values contain only a single thing (be it a string or a number or whatever). In contrast, objects are used to store keyed collections of various data and more complex entities.

r/learnjavascript on Reddit: What is an object

April 27, 2022 -

HEllo guys, so I'm learning JS and trying react but I can't grasp a good understanding of some of the, apparently, most important terms. One of them is Object, another one is parent/child components, since I seem to find different examples that aren't consistent, and it's especially difficult for me to understand the codeword this, because of the previously explained.

So, my questions are:

what IS an object in JS and what is an object in react?

How do I know what is a parent and what is a child?

How do I understand the "passing props" part of the code?

I'm doing the react turorial Tutorial: Intro to React – React (reactjs.org), and part of it is "passing props" but I just don't get how one component is taking value from another when I can't see any relation between them.

Edit: thank you, everyone, for your answers, I will keep trying to grasps the concepts I'm struggling with before proceeding with anything. An object is now much more clearer but I'm still struggling with the parent/child and the passing of props but I'll keep reading.

Shouldn't you learn vanilla JavaScript basics before diving into react?

An object is a data structure which is usually made up of key value pairs. An example of an object that you might see at an incredibly basic level is: { name: “Elon”, surname: “Musk” } The brackets indicate it’s an object, everything inside of it is the data. In this example you can identify the key as name and the value as Elon This concept is consistent across both JavaScript and especially React because after all, React is just a framework for building user interfaces in JavaScript! When we talk about the concept of parent and child, you need to understand that the way data is structured is often hierarchical. In React, we may have a component function that outputs some JSX. It might be a button, let’s say. Well, that button probably sits inside of a container or menu, right? So in this case the button is a child of that container or menu potentially. In regards to props, well, they’re short for properties and you’ve already seen them in the example above! name or surname could be considered properties, or props for short. In React, we often pass data through these component functions using props, and props are normally objects, much like you’ve seen above. In React, you may see an example like props.surname, that is just referring to our object above and referencing the surname property or key. Hope that helps :)
