Objects can be thought of as a key/value storage, like a dictionary. If you have tabular data, you can use an object to lookup values rather than a `switch` statement or an `if/else` chain. This is most useful when you know that your input data is limited to a certain range.
Here is an example of a simple reverse alphabet lookup:
Here is an example of an article object:
```js
const alpha = {
1:"Z",
2:"Y",
3:"X",
4:"W",
...
24:"C",
25:"B",
26:"A"
const article = {
"title": "How to create objects in JavaScript",
"link": "https://www.freecodecamp.org/news/a-complete-guide-to-creating-objects-in-javascript-b0e2450655e8/",
"author": "Kaashan Hussain",
"language": "JavaScript",
"tags": "TECHNOLOGY",
"createdAt": "NOVEMBER 28, 2018"
};
const thirdLetter = alpha[2];
const lastLetter = alpha[24];
const articleAuthor = article[author];
const articleLink = article[link];
const value = 2;
const valueLookup = alpha[value];
const value = "title";
const valueLookup = article[value];
```
`thirdLetter` is the string `Y`, `lastLetter` is the string `C`, and `valueLookup` is the string `Y`.
`articleAuthor` is the string `Kaashan Hussain`, `articleLink` is the string `https://www.freecodecamp.org/news/a-complete-guide-to-creating-objects-in-javascript-b0e2450655e8/`, and `valueLookup` is the string `How to create objects in JavaScript`.
