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.

If any of you are wondering how you can set up the same environment, check out this reference.

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.
