JS features a few data types, or in other words different types of content, which can be used as values of a variable. These include:
* [https://developer.mozilla.org/en-US/docs/Learn/JavaScript/First_steps/Strings strings]: pieces of text, always wrapped in single or double quotation marks <code>var name = "I am Pluto";</code>  
* [https://developer.mozilla.org/en-US/docs/Learn/JavaScript/First_steps/Math numbers] (both integers and float point numbers) <code>var discovered = 1930;</code> 
* booleans: true or false values (outside quotation mais) <code>var planet = false; var dwarf=true;</code>
* [https://developer.mozilla.org/en-US/docs/Learn/JavaScript/First_steps/Arrays Arrays] (or lists): a container of multiple values enclosed in square brackets and separated by commas <code>var planets=["Pluto", "Neptune", "Uranus", "Saturn"]</code>
** the values of arrays can be accessed by their location within the array var <code>p=planets[0]; var s=planets[3]</code>
* Object: is a list of items, each item, stored by a name-value pair. The values can be strings, numbers, lists or even other objects.
** <code>var saturn = {"moons": ["Pan", "Daphnis", " Atlas", "Prometheus", "Pandora"], "Volume":"95.159 Earths"}</code>
