# Frontend Code Challenges

Typical frontend specific code challenges

Often frontend code challenges includes manipulation of data structures, such as strings, arrays, and objects, then having to re-render the modified data into a new output. This is probably due to the fact that often times frontend engineers will be passed data from the server and would need to render that data in a particular way.

Examples of certain kinds of coding challenges may include:

* Flattening objects and arrays 
* Rendering a list of objects as an infinite looping image carousel
* Parsing data and returning that data in a particular shape
