Caitlyn loved chocolates and asked her mum to buy her a truck of chocolates. Her mum wasn't as generous, but she did buy Cait a tiny chocolate dispenser. However, she didn't teach Cait how to operate it. She would only give her one chocolate a day. Cait obviously wanted more, so much more.
Cait is now on a quest to create a virtual terminal which can directly access the chocolate machine. She needs YOU to help her code functionalities in the back-end though. Go to the src/app.js file and complete all the unfinished code to satiate her sweet tooth.

And finally, create a pull request so your ProGrad Mentor (PM) can review your work.
The src/app.js contains an array of 100 chocolates. We are talking about the 100 strings that specifies the color of each chocolate. Available chocolates are of the colors green, red, purple, blue, crimson, silver, pink.
Every function will take the chocolates array as it's first input by default.
As usual, open the SpecRunner.html file on your browser and start coding to pass the test. Remember to focus on one test at a time and read carefully the instructions to understand what you have to do.
Hundred chocolates? Not enough! We certainly need more. Create a function addChocolates() which takes chocolates,color, count as arguments and adds them to the dispenser from the top.
We have added too many chocolates and the machine has started to malfunction. Create a function removeChocolates() that takes number,chocolates as an argument and returns an array of chocolates that have been removed from the top.
Cait can't have just one chocolate a day. So our next task would be to create a function dispenseChocolates() that dispenses chocolate at her will. It takes number,chocolates as an argument and returns an array of chocolates from the bottom.
Cait is annoyed with all the green chocolates she's been getting. Time to change things up a bit. Create a function dispenseChocolatesOfColor() which takes chocolates,number, color as arugments and return an array of chocolates from the bottom of the given color.
Cait is finding it difficult to keep track of her chocolates. You'll need to create an LED that shows her how many chocolates of each color are remaining. Create a function noOfChocolates() that returns an array of number of chocolates in the order [green, silver, blue, crimson, purple, red, pink].
Cait wants to eat a lot of chocolates, but is trying to restrain herself. Therefore she has decided to only eat chocolates that are least in number. To do this though, we need to have the chocolates arranged properly. Create a function sortChocolateBasedOnCount() which sorts the chocolates in descending order of their count.
Cait wants to the ability to change the color of the chocolates now. Little does she know, changing the wrapper won't change the flavor. But, well, create a function changeChocolateColor() which takes the arguments chocolates,number, color, finalColor and changes n chocolates of the of color to finalColor
Caits wants to change all chocolates of a given color to some other color. Pretty sure she's trying to get rid of all the green chocolates. Create a function changeChocolateColorAllOfxCount() which takes the argument chocolates,color, finalColor and changes all chocolates of color to finalColor. It should return [countOfFinalColorChocolates, chocolates].
Cait believes that all the best and newest chocolates are at the top of the machine. She needs help removing just one chocolate of the given color from the top. Create a function removeChocolateOfColor() which takes an argument color and removes one chocolate of the given color from the top.
Cait has found something incredible. Combining similar colored chocolates gives us an additional rainbow colored chocolate. She wants more of these, and less of her having to combine them. Create a function dispenseRainbowChocolates() which takes an argument number and returns the number of rainbow chocolates dispensed for every 3 chocolates of the same color.
