Task 01 - Typescript

In the first task, we will not be focusing on the frontend yet, but on typescript and writing clean and quality code. We have prepared an npm project in which we have included all the necessary dependencies, which include, among others, typecript, eslint and prettier. Your task will be to add several types and implement four functions.

Project Overview

In the project you will find the following important files:

src/types.ts - a file that contains all the types you will need. This file also describes what each type represents. So there is no need to add any extra type (but it is not forbidden).
src/index.ts - the file in which you will implement all the functions. The description of each function can be found in the file, each function is annotated with a description of the functionality.
src/data.ts - the file that contains the data you will be working with. There is a jobs list and a people list. Lastly, the db object is used to simulate the database, using the data in the index.ts file.

Tasks

Start by defining the types in the src/types.ts file according to the individual descriptions or according to the data in the src/data.ts file or from the attached function call output.
Implement the functions in the src/index.ts file according to the individual descriptions. Do not change the typing of parameters and return values.
Use npm run build to run the src/index.ts file. The output in the terminal must match the attached output.
Finally, verify that your code meets all linter requirements. The npm run lint command can be used to do this.

Submission

There should be created a pull request called "Feedback" immediately after accepting the github classroom assignment.

If you have a Feedback pull request

You can push your solution straight to main. You will then see the diff against main in the pull request feedback. Once you have the solution in main, mark the Feedback PR as submitted.

If you don't have a Feedback pull request

It may be that it will be created later, or it may not be created at all... Therefore, as a precaution, create a new branch solution from main as soon as you accept the assignment, and then push your solution to it.

If the Feedback PR does not appear, make a pull request from your solution branch to mainu and mark this PR as submitted.
If the Feedback PR does appear, merge your branch solution into main, then mark the Feedback PR as submitted.
