FTR Timer Coding Test

This console application is built with Node and Typescript. It can also be bundled to a single executable JS file using Webpack. The application should operate as follows:

1. On startup, the program will prompt user for the number of seconds (X) between outputting the frequeuncy of each number to the screen.
2. Every X seconds the program will display, in frequency descending order, the list of numbers and their frequency.
3. If the user enters 'halt' the timer should pause.
4. If the user enters 'resume' the timer should resume.
5. If the user enters a number that is one of the first 1000 Fibonacci numbers, the system shoud alert 'FIB'. Entering the 1001th Fibonacci numbers will not have the same alert.
6. If the user enters 'quit', the application should output the numbers and their frequency, a farewell message and finally terminate.

Instructions

1. Navigate to a desired directory, run git clone and use either https or ssh to clone the repo.
2. cd timer-console-code-challenge to navigate into the cloned repo.
3. Minimum requirement is to have Node version 12.16.0 or above. If nvm is used to manage Node versions, run nvm use and it will use the Node version specified in .nvmrc file. To install the specific node version, run nvm install 12.16.0.
4. Run npm install to install packages.
5. Run npm start to start the interactive console program. Follow the instructions or enter 'quit' at anytime to terminate the program.
6. Alternatively, run npm run build to bundle all source files to a single executable JS file. To start the program, use the command node ./dist/bundle.js. The program should operate as normal with additional performance boost.
7. The single JS file will also be useful for situation such as deployment and hosting through a CDN. This file can be assessed at directory /dist/bundle.js after running the build command npm run build.
8. Run npm test to run all test suites.
9. Solutions for part 2 of the coding test can be found in part2.text.
