Loops are used in JavaScript to perform repeated tasks based on a condition. Conditions typically return `true` or `false` when analysed. A loop will continue running until the defined condition returns `false`.

There are three common types of loops:

*   <a href='http://forum.freecodecamp.com/t/javascript-while-loop/14668' target='_blank' rel='nofollow'>while</a>
*   <a href='http://forum.freecodecamp.com/t/javascript-for-loop/14662' target='_blank' rel='nofollow'>do while</a>

You can type `js for`, `js while` or `js do while` to get more info on any of these.
