This course compiles a comprehensive range of questions that are most likely to be asked during the frontend interview. Where many interview prep courses focus on data structures and algorithms, this course focuses on a variety of topics from network security to system design.

In this course, you will solve interview questions that cover general aspects of web development. You’ll start by going over network security and optimization techniques for load balancing and browser rendering. After that, you’ll move on to interview questions around SEO, APIs, and system design.

Overall, these are questions that are often overlooked, but they can really make you stand out from your peers. By the end of this course, you will have the confidence and ability to go in and ace that interview.

# Problem statement

A linting program is used to flag anything that may be wrong with a piece of code. More formally, "lint, or a linter, is a static code analysis tool used to flag programming errors, bugs, stylistic errors, and suspicious constructs." ([Wikipedia](https://en.wikipedia.org/wiki/Lint_%28software%29)). 

Linting can save you many hours of work in the long run, especially in a team setting, because your code will be intuitive, bug-free, and will follow common stylistic practices, all of which are usually fixed at the review stage. If they are not fixed at the review stage, then bad code goes into production, and costs the team hours of work when the code needs to be looked at again.


So, it’s a good practice to lint, and linting JavaScript can be automated with Grunt. Hence, in this exercise, use the [Grunt ESLint plugin](https://www.npmjs.com/package/grunt-eslint) to lint the file `app.js`. The Gruntfile is currently empty, and running it without filling it will throw an error. Your code is in the `/eslint` directory. To save your changes, click `Run`.  


## Sample input
