This coding test is a series of questions as outlined below. Please follow the instructions carefully.

It's recommended to use JavaScript ES6+ & React 16+ but you are free to implement your answers in any language you feel comfortable.

The time recommended is 1 - 1.5 hours, try not to spend longer than that, we don't want you to waste a precious day of your life over this. You do not need to complete all the questions.

Please commit your code to Github and share the link with us.

• Please use respective answers folder for the questions you are answering. For example, answer for question 3 will go to answer03 folder.

Implement Array.reduce() or Array.map() in your own way.

Implement Lodash’s groupBy in your own way

Given two strings, write an algorithm to check if they are anagrams of each other. Return true if they pass the test and false if they don't. E.g

isAnagram('silent', 'listen'); // should return true

isAnagram('hello', 'world'); // should return false

Given a string of text, find and return the most recurring character. E.g

maxRecurringChar('aabacada') // will return 'a'

You have a large bunch of HTML. Inside that HTML are p tags, li tags, table tags, really any and all kinds of HTML tags. Most importantly there are anchor/link tags.

Write a program to find all of the URLs to which those link tags link and verify that the URLs return a 200 response. In a given chunk of this HTML, we could have anywhere from 0 to 100+ links, so your solution should handle the case where there are plenty of links.

Requirements:

• First, you'll want to figure out a way to extract all of the URLs.

• Second, you'll want to test the URLs and report back to the user which are valid and which are not.

• Third, you'll want to make it really fast by checking the URLs concurrently or by parallelising the checks. You might want to think about caching as well.

CSS test: Apply required CSS to produce the HTML as per the result image provided.

In answer06 file in a browser. Apply required css in the styles.css file. The end result should look like the image in CSS_Result.png file.

Simple react component to implement expandable <textarea />. Very similar to this. Just basic requirements - not everything that material-ui does. Simple auto expand/contract feature.

Extend the package.json file to include your dependencies required. We expect it to be kept minimum - just required to render a React component.
